Following Yuri's Poll I noticed that Access control wasn't listed other then public waves. A while ago that issue was discussed. I'll admit I was probably the first to caution. That is becuase I didn't want access control to become inflexible by design, and I was theorising custom access control where in a broader sense you are enabling interaction control.
However I think at a more basic level it would be nice to have some of the more common broader use cases. After private, public the next most desirable access control (not suggesting pubic or private are exclusive of these). If there are a handful of common access control options, that are implemented in such a way that won't limit flexibility in the future, I think that will serve to broaden WAIB's appeal. What would be the next desirable ACs?
