The only way, imho, we could have such a feature would be related to
the corresponding Test Suite.
:isimplemented(<property>)
The UA would be responsible of making that condition true or false
if the UA passes or not all the W3C tests related to the property.
Kindof a CSS equivalent to the DOM hasFeature().
The cool thing here is that the CSS error handling applies: if the
property is not implemented at all, it's not recognized at parsing,
and the rule is thrown away. And if :isimplemented() is not itself
implemented, same effect.
