  Version field <-> Version is not invariant

...it's just a Version field.

This is a subtle one, but it follows from the work that others have been
doing on greasing versions or providing additions to echconfig for QUIC
connection establishment.  It basically says that Version is for
endpoints, not middleboxes.
