One issue (out of many, as I'm discovering) with the ATmosphere protocol, used by Bluesky, is that all data in your personal data store (PDS) is public data. There is no private data in the ATsphere. This article reports on ongoing work to change that, but it's work that has implications. "At the end of the day, specifying a new protocol scheme is basically owning up to the fact that, while we may re-use many primitives and roles from the public data protocol, we are specifying a new data and sync protocol, not just an extension to the existing protocol." Personally, I think what is proposed here is over-engineered. But the thinking is not wrong.
