Buffy did it.

None of the pre-"Season 8" comics are considered canon and there were a TON of those.

But I agree with your primary point, people want answers and they should have them. Unfortunately, writers don't want to be beholden to a bunch of strict cannon that restricts their storytelling. It's a delicate balance.
