So what would you call them ?


As soon as you start giving design concepts fancy names,

They'll do it anyhow, for marketing. If Hitachi has a class-G amplifier,
then Toshiba, even though using the same circuit, will call it class H,
simply to look original.

WRONG. Class G and H use quite different circuits.
