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 ;)

Rick pointed out that at kilowatt power levels, voltage breakdown may
not be the real design limit.. thermal dissipation in the dielectric
or copper might be the limit. It may not arc over, but if it melts
just the same, it's no fun.
