It occurs to me maybe we're talking past each other.  When I think of the *Require* header, I think of what does any random endpoint/gateway getting this request have to support for this to succeed.  I can see no value in having that behavior, and plenty of harm in doing so.  I don't want a UAC maker to ever think it can require UAS' to implement 199 in order for its request to succeed.
But maybe what you're talking about is *Proxy-Require*?
