Rather than that, what about activities stating which kind of
invitations can accept? Then the user could choose one of several
activities from the invitation palette.
But this looks like too much complexity for the August release.

Hmm, I don't quite see why the presence of a MUC should affect having
an activity_id or a private connection. Seems to me like an
implementation detail surfacing too high on the API. There's no way a
private connection could be exposed as a privately-shared activity?

No other way that I know.

Yes, if they have nothing in common, being two classes look cleaner ;)
