Hackborn starts with a stick ("I suspect we are going to need to start doing things to prevent you from impacting our app ecosystem") and then shows just a tiny glimmer of carrot ("Doing this correctly, without impacting our app developers... I also think it is something that needs to be done at the mainline platform level...")
So who knows what to make of that. My main reason for hope is that it's just so unusual for Google to speak out that way. All kinds of bizarre things get added to ROMs and they just ignore it. Then this comes and the Google engineers go bananas. It has to mean (or at least, I think it has to mean) that they have some plans around it, and they really don't want something incompatible coming out and becoming a defacto API ahead of that.
