These are welcome changes but I hope they will address the elephant in the room sooner or later. They can't go on depending on Pixels and hardware memory tagging. They need a roadmap for opening up the project to more phone models and they need it yesterday.
They've drummed up some publicity with the journalist debacle so it's a good time to use that. But people who hear about Graphene will want to have some phone choices. "Get an old Pixel" is about to age like milk.
