I've always left them on, and never had any issues...(even after unscheduled power loss - which happened here yesterday). As I understand it, the softupdate code reorders *metadata* operations, and does not alter data operations - so the effect of fysnc(2) on a preexisting file is not changed by softupdates being on or off.
This is also my understanding, and I also leave softupdates on for the data partition. Even if it doesn't improve performance, it will not reduce it, and otherwise does no harm with respect to postgres' disk usage.
