Now THAT is the most sensible and probably accurate reason I've heard for removing the PC socket. I can get by with an adapter on the hotshoe if an in-body socket compromises the seals... A (Programmable to work with different receivers) radio trigger would be even better...
btw, there seems to be some misconceptions about what the PC socket is for. It is for attaching a corded flash unit, not for attaching a PC... there is already one on the K10D for that.
