If a guy used 430.52 to size his breaker and ended up with a hard wired pool pump on a single pole 30, he would not need GFCI.
(B) GFCI Protection. Outlets supplying pool pump motors from branch circuits with short-circuit and ground-fault protection rated 15 or 20 amperes, 125 volt or 240 volt, single phase, whether by receptacle or direct connection, shall be provided with ground-fault circuit-interrupter protection for personnel.
I have heard a couple of discussions about the 10a breaker thing. The first issue is the number of 10a circuits you would need to get the 3va per sq foot. That might be a show stopper right there. The other one is the 210.21(B)(2) problem.
I have heard a more compelling argument if the 10a only served the smoke alarms. That could make some sense.
