Neat idea but I don't get how it works with feature rollouts. If Gmail is updated which changes the DOM and breaks the API how does the SDK handle being updated when it's rarely a change that's rolled out instantly for all users (usually takes some time maybe even weeks). I mean you either have a TON of feature testing to figure it out or you let it break; neither of which seems very maintainable to me. What's going to happen with the rumored update? I've been hearing rumors for over a year now that gmail, calendar, contacts and even tasks are being majorly overhauled; is there any collaboration with Google to make sure when (or if) these rumors come true that it won't simply break everything day one? Trying not to be a nay sayer; this is a great idea if you want to quickly add something to Gmail without messing with the Gmail DOM yourself but it doesn't seem to be a good long term bet to me.
