Thanks! Don't we need to provide an implementation for those? Or it's already there?

It's already there, it has been added when upgrading jupyter-collaboration to v3 #204

Don't really know why it did not fail from the beginning.

jupyter-ydoc is pinned to >=2,<3 here, but @jupyter/ydoc v3 is allowed here. Isn't that a problem?

We should update it, but I don't think there are breaking change on the python package between v2 and v3. It doesn't seems to be an problem.

I don't think we should look at code and try to guess if major versions are compatible, this is very error prone.
