Agreed!
However another factor in the design process is the duty-cycle of the
mode. Voltage breakdown is likely to be pretty much instantaneous and
mode independent; but excessive thermal dissipation will be associated
with a time constant, and depend on the mode.
Then again perhaps you folks are all running 1.5kW 100% duty-cycle RTTY ;)
