Thoughts on Promises
AKA, can we just ship 1.0 already
#1: We need to support the current gUM API.
#2: We need to retrofit Promises to other APIs (e.g. XHR).
#3: Ergo (#1 + #2), we can retrofit Promises to gUM.
#4: We need to finish 1.0
#5: Adding Promises will make #4 take longer.
#6: Promises will not drive adoption of WebRTC 1.0.
#7: Ergo (#3 -> #6), we can and should add Promises later.
