It mainly makes me pine for linux phones. I think Graphene is the best we have at the moment in the mobile space, but that's far more of a testament to our lack of options than how valuable Graphene is. I have no doubts that we'll eventually kick Graphene to the curb when it stops being useful, so I'm not overly concerned with its future. Worst-case, I think many of us would be just fine on any other AOSP rom for a few extra years until linux phones can come save us all.
