@simon @amyhoy @natematias @dansinker @jessamyn @danhon @ryanrandall speaking as, I think, the only highly experienced ActivityPub dev on this thread, Simon is right, this kind of permission granting is anywhere from extremely hard to impossible in the ActivityPub model unless you just want to set a flag that says "please respect this flag and don't allow your users to QT".

But crucially: that may be enough! It's how "unlisted" posts work.
