You still have to charge the gate of the switch through the finite resistance of the pass-gate. This is slower than an active driver, particularly at the low corner.
The alternate is a (comparatively) large driver driving one end of a weaker (order of magnitude) keeper. This is usually faster at low voltages and is the more common latch at the high end.

COMMERCIAL? You mean as in practical? I've been talking from the logic-theoretical standpoint, where the "all logic can be made from 2- input nand (or nor) gates" mantra comes from.
Ther you go, changing the subject.
That always seems to happen in these religious discussions.
Oh, cripes! Another leftist weenie ;-)

I love to cook with wine. Sometimes I even put it in the food.
Many early minicomputers did just that. The Interdata model 1 among dozens of others.
