We could certainly make the optimization of grouping each "set" of 
constraints in one object instead of making a new object for each 
constraint, and I think Dan did have something like this in his original 
proposal in the form of a "Constraint Set", IIRC.

So, my preferred syntax is, as an example:

navigator.getUserMedia({
   video: {
     mandatory: {
       videoMinHeight:600,
       videoMaxBandwidth:500
     },
     optional: [
       {
         videoMaxAspectratio: 1.333333333333,
         videoMinTimebetweenrefframes: 20,
         videoMinFramerate: 30,
         videoEnumAutowhitebalance: "on"
       },
       {
         videoMinTimebetweenrefframes: 40,
         videoMinFramerate: 10
       },
     ]
   }
});
