What's the state of server-side frameworks with Kotlin support today for small teams?
You named Express as an example for a good framework - I'd say both http4k and ktor come close to it. Spring Boot would really be on the other end and I met lots of JS/TS devs that didn't even want to touch it. I did have the same impression than you though: Documentation for ktor is not great at all.

Which backend Frameworks for Web App is easy to learn?
http4k has excellent documentation and very simple concepts.

Application-as-a-Function Thinking
I couple of years ago I was lucky to use http4k, a server as a function web library for Kotlin. It was such a wonderful change compared to every other technologies available in both Java and Kotlin. It's simple.
Testing becomes so much easier too, as one can instantiate a the whole web routing aspect, without having to bind it to a port and having to send real http requests.
If strongly suggest people to take a look at it. It's not perfect, but it's a lot simpler than other frameworks and libraries. And it's a shift in some of the current mentality of using heavy frameworks (such as spring boot) which blow up anyone's cognitive load.

A Tale of Two Connection Pools
I found one suggestion from the author of HikariCP on how to address this, which I implemented and it worked. However, there are additional classes involved, and it feels a little clunky and hard to follow.

Spring boot change password runtime
Not really, you can change some things in spring boot but doing so will typically trigger a refresh which is less reliable than restarting but still causes a large performance hit. You could probably do it with hikari if you really needed to but it's inadvisable to build your application around this mechanic.

Should I use diesel ORM if performance is the most important thing?
Whatever you choose, presuming your app is database heavy, I highly recommend spending time on DB schema design to make all queries as short as possible, avoid relying on transactions, and keep your connection pool tiny.

Art of README
You reminded me of the HikariCP library and it’s documentation: Clear and simple with references to other libraries trying to accomplish the same thing. It is not in the closure space though.
