I doubt GPS could be trusted for autopilot, but if the accuracy is reliable for a ~30 foot sphere it could be used as a proximity alarm. ("Cool your jets human, there's another drone nearby")

The GPS on my iPhone is good enough to pinpoint my 2D position to within ~10 feet, so I don't see why not.

GPS is good enough for autopilot; I've flown with them just fine. It's also common to do GPS approaches in inclement weather, and when you break out of the clouds, the runway is right where it should be!
