I have to say, I agree with @jdormit@mastodon.technology regarding ActivityPub being something that we need to work with compatibility rather than always making improvements to the protocol. Yet there are always improvements. to be made; hopefully new implementations of the protocol will consider adding all of the features; seems like there are lots of things stipulated by the specification. the problem? Not enough implementations use it, and one implementation is very different from another. So, not only do we need to consider compatibility, but we need to also consider unused features; instead of improving the protocol, actually use what's there, but currently not doing anything ...
