Yeah now that you mention I read this a while back.

I also commented on it but somehow left it in draft.

...Reading through these and the issues associated with it is very useful but still leaves some confusion in my mind.

Managed/unmanaged groups, nested groups, combination of these, rooms, relay support, relay implementation dependency, feature detection...this is the most confusing spec in that I really find it hard to identify the use-case I want to go with.

But this won't stop me from taking steps toward my plan. I think I know now which way to go.
