It seems like some major players within the Bitcoin space now also support BIP101 so this is certainly far from done.
That was also true months ago, so little has changed. And to be fair, for "major players", read "major banking industry subversives/captives".
I challenge you to get real Bitcoiners to use Gavin Andresen's non-fungible alt-coin if a fork took place: why would a Bitcoin user be interested in something that's planned to become fiat 2.0?
