Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

topoconfig: enhancing config declarations with graphs
Meanwhile, formats have been evolving (JSON5, YAML), config entry points are constantly changing. These fluctuations, fortunately, were covered by tools like the cosmiconfig.

That's a Lot of YAML
I think JSON5 is fairly close to this: https://json5.org
I reckon the only thing it's missing to be truly accessible to non-techies is that string values still need to be quoted, i.e. you can't have:
key: this is my value
(I'm definitely not saying it would be a good idea to allow quotes to be dropped, just that that's the only potential stumbling block I see for non-techies.)

XML is better than YAML
I believe that's JSON5.
https://github.com/json5/json5
It's my preferred configuration file format, it fixes all the problems I have with JSON (trailing commas, comments) without turning it into a mess full of gotchas like YAML.

TySON: a native go library that lets you use TypeScript as an embedded configuration language without depending on Node or V8
I would like to see mention of JSON5 which is 11 years its elder. For comments in JSON, JSON5 is a good starting point.

XML is better than YAML
I don‘t understand why HOCON (https://github.com/lightbend/config/blob/main/HOCON.md) isn‘t used more often (at least for configuration use cases). It‘s a superset of JSON, has comments, multiline strings, optional quotes, replacement syntax. We use it at many places, and it‘s as nice at it can get.

Ron: Rusty Object Notation
HOCON is a great human-readable alternative to JSON. It's a superset of JSON with lots of cool features that make it both more readable and easier to use.
Here's a rundown of HOCON's main features: https://github.com/lightbend/config#features-of-hocon

Spring and scala
"Typesafe Config" is the library generally used to read configuration files in HOCON format, which this library introduced. It's commonly used in essentially OOP/imperative Scala contexts, including Akka and its ecosystem.

Make systemd better for Podman with Quadlet
Interesting!
For my own servers I use an internal tool that integrates apps with systemd. You point it at the output of your build system and a config file, and it produces a deb that contains systemd unit files and which registers/starts the server on install/reboot/upgrade, as a regular debian package would. Then it uploads it to the server via sftp and installs it using apt, so dependencies are resolved. As part of the build process it can download and bundle language runtimes (I use it with a JVM), it scans native binaries to find packages that the app should depend on, and you can define your config including package metadata like dependencies and systemd units using the HOCON language [1].
Upshot is you can go from a Gradle or Maven build to a running server with a few lines of config. Oh and it can build debs from any OS, so you can push from macOS and Windows too. If your server needs to depend on e.g. Postgres, you just add that dependency in your config and it'll be up and running after the push.
It also has features to turn on DynamicUser and other sandboxing features. I think I'll experiment with socket activation next, and then bundled BorgBackup.
Net/net it's pretty nice. I haven't tried with containers because many language ecosystems don't seem to really need them for many use cases. If your build tool knows how to download your language runtime and bundle it sans container by just setting up paths correctly, then going without means you can rely on your Linux distribution to keep things up to date with security patches in the background, it means networking works as you'd expect (no accidentally opened firewall ports!) and so on. SystemD knows how to configure resource isolation/cgroups and kernel sandboxing, so if you need those you can just write that into your build config and it's done. Or not, as you wish.
With a deployment tool to automate builds/pushes, systemd to supervise processes and a big beefy dedicated machine to let you scale up, I wonder how much value the container part is really still providing if you don't need the full functionality of Kubernetes.

Introducing JXC: An extensible, expressive data language. It's a drop-in replacement for JSON and supports type annotations, numeric suffixes, base64 strings, and more!
Other similar standards: TOML, HOCON

Jsonnet is better than YAML for generating JSON
I've also used HOCON pretty extensively for config, and it is better than both YAML and JSON for config with moderate to high complexity.
What are some alternatives?
Json.NET - Json.NET is a popular high-performance JSON framework for .NET
cfg4j - Modern configuration library for distributed apps written in Java.
hjson-js - Hjson for JavaScript
owner - Get rid of the boilerplate code in properties based configuration.
jq - Command-line JSON processor [Moved to: https://github.com/jqlang/jq]
dotenv - Loads environment variables from .env for nodejs projects.
toml - Tom's Obvious, Minimal Language
dotenv - A twelve-factor configuration (12factor.net/config) library for Java 8+
jsonnet - Jsonnet - The data templating language
Configur8 - Nano-library which provides the ability to define typesafe (!) configuration templates for applications.
sublime-hjson - Hjson support for Sublime Text
centraldogma - Highly-available version-controlled service configuration repository based on Git, ZooKeeper and HTTP/2
