That's really odd. What's wrong with { width: true, height: true,
aspectRatio: true, ...} other than the fact that
MediaStreamTrackConstraintSet (or whatever it's called) doesn't permit
that syntax? Is this just an attempt to avoid creating a new,
parallel structure?
It's possible to use a named properties structure here, isn't it?
http://www.w3.org/TR/WebIDL/#idl-named-properties
interface ConstraintSetSupports {
getter boolean (DOMString constraintName);
};
With the set of names being defined in text. This would have the
advantage of being extensible.
