not really - this all is early POC. Unclear if ever officially released .... I see no reason to invest into documentation at this point in time
@kobergj you call - I'd close this

Note, this issue is a reminder.
I do this for all potential doc changes.

It will be closed when the referenced PR gets closed.
But if it is merged, I can find it easily to add the relevant docs for.
