If I wind up making a Bluesky PDS what this will most likely look like is some relatively (God, I hope) small block of code that connects to mastodon.social once an hour, reads my Mastodon feed like a regular client, and then republishes it into whatever format PDSes publish timelines in. And then I guess my profile just says "I cannot read your replies, join some actually federated network if you want to talk to me"
