Generally, Github Issues are used as a bug tracker, not a community FAQ. Asking a maintainer to compare and contrast their project with another project or git feature seems a bit demanding.

Keyword: generally. Plenty of projects do allow community questions, specially small ones or early stages. Is there anywhere else to ask that question? If there is, it isn't prominently signified, answering at least "ask this >here<" would be common sense. At a minimum, this issue evidences the need of documentation and should be addressed in some way with more than "I don't have to answer this".

GitHub Discussions is a much better place to handle Q&A: https://docs.github.com/en/discussions

Which didn't exist when that issue was created.

And none of the people in this thread did provide even a hint of an answer either...

It's not a trivial question, so it's not that surprising that nobody answers it without prior knowledge of the thing?

There is now an answer to the question in https://github.com/esrlabs/josh/issues/23

I wouldn't even agree that it's not an issue. It's something the README doesn't cover.
