I get the DAV-collection-implies-non-uniform thing, and would be
against a revision which attributed that meaning to a 201 response.
But I'm just not seeing how ADDMEMBER==POST, sorry.

I still don't see how POST vs. ADDMEMBER is any different than POST
vs. PUT.  You previously said that PUT has "set the state of this
resource" semantics which is clearly different than POST.  IMO,
ADDMEMBER's semantics are very similar to PUT.  What (constraint?) am
I missing that suggests PUT is fine while ADDMEMBER isn't?
