Has anybody setup their own at-protocol PDS and indexing infrastructure and tried to interact with Bluesky without using their resources?  Such a thing is *critical* to their decentralization story.  The had better have been doing this since day one, and making sure that their changes never break these self-hosted users, otherwise "decentralization" is just an idle academic claim with no proof (how many people are doing it?  zero?  Not very decentralized I'd say).
