My answer is that it depends. I know several divers who started diving specifically so the could dive caves. They have done thousands of dives but probably haven't done a dozen in OW. They were experienced cavers though and the purpose for the diving was to get through the UW portions of the cave...cavers who decide to continue into UW caves as apposed to divers who decide to continue into water that flows into caves.
Here in the US we tend to be divers that decide to dive in caves. It isn't that way everyplace or for everybody. The CDG is probably a good reference here. They do it differently and the dive training is aimed at cave diving from day one. I think they tend to be cavers first. I'm a trained cave diver of modest experience but I'm not much of a caver. I just dive in caves.
One way or the other, we all have to guard against going too far too fast. I guess the specifics of that depend on your starting point.
