Maybe, coordination is the problem. What does that data look like, what does the target look like, can they be transformed?
ATProto has lexicon, which are more about social coordination than schemas for data correctness

The protocol is much more than data portability, it essentially turns the global social media system into a giant distributed system anyone can participate in at any point. Imagine if FB also let you tap into the event stream or produce your own event stream other FB users could listen to in the official FB app. That would be a pretty awesome requirement for all social media apps, yea?
