Someone pointed out in another thread (or maybe it was this one... it's so hard to keep track), that Granny was EXCEPTIONALLY rude to Cruella. To the point where she's never even treated Regina in such a way, not even in season 2. So I think they were foreshadowing (as implied above) that Granny's Anita is Cruella's Anita. They said we wouldn't see the 101 Dalmations story as we know it, they never said anything about its characters. And it'd be a shame to waste a character that could give Granny some much needed and much wanted depth.
