Not really. If you still buy books at stores, you'll want your Atwoods all shelved together, as opposed to her literary work being in "fiction" and her sci-fi work being shelved in "fantasy & science fiction"
I am trying real hard here and I really can not remember when I last bought a book for myself in a store. Last year in Berlin when I bought some Banks novels for a friend, that was an impulse buy because he did not know any of them yet was the last time I bought books in a store in general, but they were not for my own use.
I'm mostly an online buyer myself. But when I go to book stores I've noticed the sorting associates the genre with the author and not with the work. This is why authors who want to write in different genres do so under pen names. So if Atwood mostly writes literary fiction, it makes sense that she would want her speculative books shelved in their usual space. This is an old mode of thinking, admittedly, but it makes sense in terms of moving physical volumes.
