Yeah, I thought about that, but the more I study it, the more I don't
see why HTTP needs to get involved in either activity.

All this stuff can be done with existing HTTP mechanisms, by defining
a new C-E which carries its own metadata in the body, like all other
C-E's, and the enourmous advantage of that is that it is backwards
compatible.
