why doesn't social-app just send the service proxying headers wtf tho I guess that would complicate pds-level implementation of preferences and stuff

It does now

(only on web waiting for app to get released)

do any of the PDS migration tools migrate preferences btw also does the reference PDS implement them itself or does the appview do it

I'm not aware of any migration tools that don't migrate preferences

wow atproto private data is here
