However, I think that what this tag can be used in addition is for designating a driving - you (kind of :-) ) play golf there, but it is not a golf course. See my comment at Talk:Tag:leisure=golf_course about that as well.
Another use for the tag would be for indoor golf, and for golf simulators. Indoor golf is often a (short) driving range and some (artifical grass) practice facilities, while a simulator means you have enough space to make a swing and shoot the ball for 2-3 meters into some kind of wall, while sensors compute and the simulator visualises how your shot would have been. Not sure how these should be tagged.
==> It is in some way, a difference IMHO is that swimming can be done in really many more places - pools, rivers, lakes, sea/ocean, ...,
