I don't think you should fix it in this patch...but FYI I don't think we need
"future" anymore. That was just there to support Apple's development cycle where
they wanted a name for internal OS releases that hadn't been named yet.

Dirk, am I correct here?

Correct, We don't need to keep this around.
