IME, you should find an official place for it soon. There are JS quirks that you have to deal with. For example, despite having been continually tested back to FF 2 and IE 6, our account login screen actually didn't work in IE9, to everyone's unfortunate surprise! If even 1% of your former IE8 users can't use stuff, it's a problem.... -- S.
