@hallenbeck I would very much like to have the Bluesky team join the SocialCG and bring some of their work to AP. That'd be great; that's how open standards work.
Unfortunately, I don't think it's possible to do without them joining and signing a patent pledge (which every participant in W3C projects has to sign).
Others can't proactively go through their protocol to pick and choose features, because if there are patented parts, we will poison AP.
