Where would we put this information optimally?

CONTRIBUTING.md or our docs?

Perhaps both places?

When docs are written in two places decoupled from each other, one will fast get outdated and ignored. I would like to have one source of truth.

Maybe we could generate/include the docs page from the CONTRIBUTING.md.

@since is required now. #1337

The jsdocs part will be handled here: #1397

What is missing for this issue to be considered "done"?

Most of our code styles are enforced by eslint anyway. If we want a mandatory code style, we should configure a rule that handles that.
