A very counter-intuitive result: most people would not consider a stable API to let you iterate quickly!

I think the article says that the API is stable unless you have access to "Alpha" and "Beta" channels.

Alpha and Beta channels only affect what client you get. All client versions talk to the same API, so it has to be very stable/backwards compatible.
