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.

Protocol on top of USB HID
I would love to see the kind of HID solution that you describe paired with a proper strongly typed message format like eRPC. In previous searches for similar messaging, I have also found things like EmbeddedProto and nanopd. I never got to dive into the details on any of these, though.

Does anyone have a protocol for the communication between microcontroller and PC?
I've seen people mention Messagepack, Asn.1 and Nanopb, which are data serialization libraries. Since in your example you mention that your protocol is like {START_COMMAND} {MODE_BYTE} {MODE_LENGTH} {MODE_DATA} I suppose that what you want is not only to transmit data, but also commands. I believe that RPC (Remote Procedure Call) is what you're looking for. Unfortunately I haven't found any really mature and well-known RPC frameworks for embedded. There is eRPC, but it is not so actively maintained. The RPC module from Pigweed, a embedded toolkit from Google, looks promising but IMHO it's a work in progress (especially the documentation is quite lacking).

Cap'n Proto 1.0
I don't work at Cloudflare but follow their work and occasionally work on performance sensitive projects.
If I had to guess, they looked at the landscape a bit like I do and regarded Cap'n Proto, flatbuffers, SBE, etc. as being in one category apart from other data formats like Avro, protobuf, and the like.
So once you're committed to record'ish shaped (rather than columnar like Parquet) data that has an upfront parse time of zero (nominally, there could be marshalling if you transmogrify the field values on read), the list gets pretty short.
https://capnproto.org/news/2014-06-17-capnproto-flatbuffers-... goes into some of the trade-offs here.
Cap'n Proto was originally made for https://sandstorm.io/. That work (which Kenton has presumably done at Cloudflare since he's been employed there) eventually turned into Cloudflare workers.
Another consideration: https://github.com/google/flatbuffers/issues/2#issuecomment-...

How do AAA studios make update-compatible save systems?
If json files are a concern because of space, you can always look into something like protobuffers or flatbuffers. But whatever you use, you should try to find a solution where you don't have to think about the actual serialization/deserialization of your objects, and can just concentrate on the data.

Choosing a protocol for communication between multiple microcontrollers
Or, as an alternative to protobuffers, there's also flatbuffers, which is lighter weight and needs less memory: https://google.github.io/flatbuffers/

Is using Flatbuffers to parse sensor data a bad application of Flatbuffers?
As the title suggests, I am considering using Flatbuffers as a way to parse sensor data that has been stored in local datafiles. The project language is python.
What are some alternatives?
