I'd be very excited to get in if even as some kind of back-up. The process of applying to grad school is very humbling, something useful for artist who are more often than not egotists or narcissists of some type, myself included. I won't pass up on some humble pie.
But to your point, it is really annoying that they would have the audacity to tell you two weeks out. For myself in particular, I only applied to one graduate school because I was on the fence about whether I wanted to go or work for another year, so I only applied to my first choice. If I had got in, I would go, if not, I'd just work for another year and apply to other schools next year.
I just hate to wait. I don't mind eating the humble pie, just not months old humble pie please.
