Great find, finally we have a official documentation of this interface. At least as official as it will get.

[Guzz-T]

I just noticed that there is more to do here. I'll get back to you as soon as I'm done.

I've put it into WIP, so it won't be merged by accident ;-).

[Guzz-T]

The pull request now contains a large number of changes. However, all of them have been added based on new findings from the documentation. Would you prefer to split these changes across several pull requests?

[Guzz-T]

Rebased branch onto main -> ready for review

Nah, for me its fine to proceed here. You've split it into multiple commits anyway.

Overall looks good to me, happy to merge this. Have started some (small) discussions for some lines (see above), but no big strategic topics, etc.
