Permissioned data is being worked on! It’s difficult since Bluesky is built on atproto and data is decentralized but it is something they are trying to do
Kinda? This is an off protocol way to do it. It requires a separate server and isn’t a very agreed upon standard. The end goal of permissioned data in atproto is to have all data stored on the users pds. This will mean it’s available across all providers and self hosted as well.
Yeag
I know Northsky has them but I still haven’t received my invite there (and even then they might not be compatible with whatever bsky comes out with…)
