As written UPGRADE only applies to the current transport layer connection
and only to incompatible protocols. While there is a possiblity that
it might be re-written to provide a subsequent connection hint as well
as my suggestion, I think one could easily postulate that certain
upgrades would truly only apply within a connection and never as the
initial state of a new connection so there would be a conflict.
