My $0.02 worth:
I think you're right that's dubious that what this sentence implies
would ever come into play. My concern would be that some idiot will
say "Well, see, right there is says that the times are a'changin', and
you're gonna have to accept it sooner or later", even though that's
not at all the intent of that sentence.
I think that what you're saying in that sentence is true -- that a
future RFC/STD could in theory make it permissible to do -- but I also
feel that doesn't need to be said. After all, RFCs have been
superseding other RFCs for years. This document doesn't need to grant
permission to its descendants to do so.
That said, I don't think that verbiage is the end of the world (and
its encapsulating para is a world of improvement). IMHO, I would drop
that sentence. But I could live with it, grudgingly, if that was the
price of moving this forward quickly.
