My home, which was was built in the early '60's, has the light switch for the main bathroom located directly above the rim of the tub. I've wanted to move it, but there is no other place to put it unless you want to walk halfway through a dark bathroom to get to the switch. So I guess I'll leave it where it is for now.
I would say that the intention of the code is to keep ALL electrical devices - except those specifically rated and permitted - out of "the zone." Granted, that many bathroom designs pretty much require that the receptacle or switch end up inside the zone, in which case, I guess we just have to deal with it.
