Even though it is a disgusting issue, it is a real issue, pretty much on topic.

And despite zillions of dollars wenting into it, if it would be just the smell, I believe it is possible someone just would have said, deal with it, there are bigger concerns in space, like keeping people alive.

(but charcoal filters work, like someone else pointed out)

And since you cannot really shower in space, I doubt the smell is the nicest up there.
