I think ":changed" would be a better name.  An ":unchanged" selector
might also be useful.

I don't see why you can't just define it to turn on when the first
change event fires.  Or use some other definition that already exists
in HTML5.  These definitions are already vague enough to accommodate
different input types, while still being well-defined in practice for
the input mechanisms in common use (e.g., text boxes).
