Some districts do that, LWDC sometimes does but I think historically they tend to do it if the revision is temporary or optional. It may have been called H10/2A when it was first changed, and then the A dropped once everybody had effectively forgotten the old course. If the H25/2 got a new letter every time it changed, we'd be riding the H25/2K by now
