More ad hominem from the usual suspects. I do not care who writes the code, what matters is what is in the code itself. Even if the code was written by the devil himself or any other monster from the annals of history, I would still support it, because the code that is within BIP101 does represent the best path for Bitcoin going into the future, compared to the alternatives.
Block scarcity is a important economical feature of bitcoin. Assuming Bitcoin will keep growing and growing is not the answer. Block size should scale according to demand, not according to assumptions. That's the only thing I have against BIP101
