That is in effect what I’d like to say, but I was hoping to have it
written with stricter requirements than just “analagous”.  Perhaps that
is not possible for the POST case while still being useful.

Well, yes.

Sure, if people want to disregard specs they will.

But, as I say in my reply to Maciej, given that it is just that the
underlying protocol is HTTP and that the request URI could just be
replaced with one that has the http scheme, I think it’d be safe to drop
this requirement.
