If you are going to have such a broad group as "science fiction and fantasy" then yes, I would lump all those together. That doesn't mean they don't fit other groups though or that I wouldn't classify them as something else first.

I think the sub-genres are more interesting and relevant. SFF is just a catch-all for anything that has magic or advanced technology or otherworldliness. It's a very broad but shallow description. (Covers a lot of things but doesn't have much meaning.) It's the sub-genres in SFF or the other genres that could cover the book that begin to have depth/meaning.
