one cool difference between Bluesky and Mastodon (et al) is that server choice on registration is not an immutable permanent decision and you can choose to seamlessly migrate at a later time by updating your DID document

so the slick registration flow nets you less lock-in compared to if e.g. the mainstream Mastodon app were funnelling users onto one megainstance, since you can still get away afterwards without needing people to re-follow you
