+1 from me. My gut feeling is that content-replace is more of a content
apocalypse in terms of implementations. I don't think it's reasonable to
expect people to have to diff content descriptions and transports in
normal operation - it should have a similar semantic/behaviour as
content-remove and content-add delivered simultaneously.
