Like E-Stat said, sliding bias systems have be around for a long time. They purport to adjust the bias up or down instantaneously according to the power demand. They don't have to continuously bias for maximum rated power and accordingly power supplies can be more modest than full-time, maximum bias devices.
I don'd have a personal opinion about how well this approach works in practice.
