Maybe so. But without that intent (and a sane cap on the amount of influence of small miners), BIP100 is IMO palatable. I'd still prefer BIP101 due to simplicity. I think that the big frontend players (Coinbase etc.) who supported BIP101 should start advertising for it soon. Because the whole 'we're independent, we'll simply stay out of the debate' approach doesn't work anymore anyways. The community broke apart and now it is a cold harsh world of many special interests fighting for their territory. I guess it has been that all the way, but now that reality is very visible.
I also expect (due to the breakup, the whole discussion is very much in a lull, should I say hangover?) that the former 'Core' developers won't be the ones coming ahead out of this. Basically, if Greg had decentralization in mind, it will soon be visible that he lost the last grip and power he had on influencing his beloved decentralization by completely overplaying his hand.
Development decentralization OTOH, I very much welcome and I expect it to be a clear to most parties that this is very much the case now, soon.
At that point, I'll also expect development to pick up again (in the various implementations of the various factions) - and the fight for influence of a particular implementation to be more open, even more political, but also more honest.
