I think you’re near enough alone… Python is up there with the best ways to call other people’s code, due to the support for types beyond string…

I think it only blocks one way, it has to be mutual to block it both ways

That just gives meta more reasons to make extensions to activitypub, or a fork, without consulting others first as nobody’s even working with them…

If they’re federating then at least they have some interest in keeping things compatible
