Given that these getters/setters are syntactic sugar for
getPropertyValue and setProperty, I'm not that concerned about this.
The syntactic sugar is important for JavaScript; in languages where
it doesn't make sense they can use getPropertyValue and setProperty.

I'm opposed to having an observable distinction between how existing
CSS properties are exposed and how new ones are exposed.  This seems
likely to interfere with techniques that authors use to detect
property support in browsers.  (I'm fine with variable properties
being different since their names aren't known in advance.)
