Is the RBF update being rushed through by Mike Hearn his next move in the Bitcoin (core developer) civil war? I don't personally see this as an update but it could well be an actual act of sabotage. Or hasn't he just come out and called the Bitcoin experiment a failure and walked away from core development. If so then his proposed update (act of sabotage) hopefully won't be implemented at the next bitcoin core update.
Mike doesn't have core commit rights, here's mike talking about it.
