Interesting observation.
Where does all that common mode energy go, if not into heat ? Does it
get converted to useful RF power, or is it dissipated someplace else in
the system ?

Okay, let's put in those K9YC multiturn chokes at each feedpoint.
This
provides a -resistive- load to the common mode path. In fact, these
chokes can get pretty warm. So, the way I see it, putting in common
mode
chokes does nothing to reduce the system power loss that K2AV is so
concerned about.
The thing about resistive common mode chokes is, the higher
their impedance, the lower the amount of power lost.
Put a choke with over 1000 ohms of impedance into an antenna
system with 35 ohm impedance, and the losses will be quite
small.
