Erm... having a prominent, admirable, lesbian character wasn't controversial?
Anyway...
We live in the era of Ellen DeGeneres on one side of the Atlantic and Claire Balding on the other, so no, that's not controversial at all.
It's weird though that DC has become so risk averse, this is the company that let Alan 'completely fucking crazy' Moore write for their flagship characters and has an openly gay Green Lantern. It's not as if comic book continuity is set in stone anyway, there are so many retcons and counter-retcons you need a flow chart just to track one character.
I suspect there's more to this than just cold feet upstairs about plot arcs, although I doubt it has anything to do with the writers and everything to do with the egos of higher ups.
