Higher frequencies also are associated with low inductance primaries, small toploads, small Cpri's, and other things that generally are associated with sub-optimal performance.

For a given power level, as the number of transfers of energy per unit
time increases the energy of each transfer must decrease. Otherwise we
would get free energy;  a direct violation of the second law of
thermodynamics.
