Well, like I said, the only way to browser-detect with the !supports
approach is to use no-ops, which aren't overly common in CSS.  Worst
case, it limits the number of prefixed attributes that UAs end up
having to support due to them being used for browser-detection to a
very small number.  (And they can then turn them into true no-ops, if
they so choose, that are only recognized as being supported but that
have no effect.  This is almost as good as phasing them out entirely.)
