So then shouldn't one expect coax to be heated uniformly along its
length at a high SWR?

No, any and all heat is work done by traveling waves, not
standing waves. As long as standing waves exist as standing
waves, they are incapable of doing work or heating anything.

You, of all people, should appreciate that since V*I*cos(90)
equals zero for standing waves, absolutely no work can be
performed by a standing wave. If the energy in a standing
wave is used to provide work, the standing wave ceases to
exist as it does at key-up.

In trying to get any work out of V*I*cos(90)=0, blood out
of a turnip comes to mind.
