You are exactly right if you're driving a car with real 4-channel ABS.
If you drive a FWD car with a lame 3-channel system, the system works
great in a straight line. But, the second you try to trail-brake into a turn
the inside rear tire gets "unloaded" and causes the ABS to over-react.
Thus, leaving you with a brake pedal rammed in your face and not enough
weight transfer to minimize understeer.

This is exactly what I was looking for, a discussion on the legality of it.
So far the general consensus is that it is not legal.
