This should work out well for the 0184 'chat' use case. I'm not sure
what happens if somebody sends an 'error' or 'headline' with an 0184

That sounds reasonable to me, could you please change 0333 to mandate
the usage of type=chat?

Currently, there is no <copy/> hint, it needs to be created first. I
suppose I was one of the many people who didn't realize there is an
actual use case for it.

I'm not sure what our alternatives are. A special element in 0280 that
provides the opposite meaning to <private/>, which is currently getting
kicked out in favor of 0334?
We could add to the Carbons rules "a message that is a reaction to a
message eligible for carbon-copies", but that is going to add headaches
to server implementors.
