@soapdog it would be very mixed. Posting in self hosting be more trivial, but loading a feed would require querrying hundreds or thousands of servers.
Particularly when thinking of all the dead/inactive accounts that would need to be queried...
And those queries would be a bit expensive.
It would also radically reduce the reach of public posts, they'd only be visible on other servers after a follower had refreshed their feed, this would break public feeds
