This is still a slippery slope argument. You're assuming that the Bitcoin ecosystem is so stupid that they will adopt just any change no matter how destructive it would be.
It's not stupidity. It's just that most people in the ecosystem are formulating an opinion based on a fraction of the data and possible implications.
If so, then Bitcoin is doomed anyways and we should just all give up. If there are no arguments pro core and/or against this XT implementation then I don't see what you're trying to say here.
I'm saying leave the experts of the core team to do their work. They know what to do and they're doing it well.
PS. You can disagree with Gavin, but to suggest that he doesn't know what he's doing warrants a bit of an explanation. I would be very interested to hear how he went from chief scientist to bumbling ignoramus.
Well, if avg block size is currently at 0.4mb (and even that is full of dust / spam txs which will be wiped out once fee competition starts for 1mb inclusion) and he says we "urgently" need 8mb and pretends that this is a very serious reason to fork it while in the process creating a rift among the devs and risking market uncertainty, well... you don't need to be a rocket scientist to realize that something very fishy is going on.
I don't believe he doesn't know what he is doing. He probably knows full well. It's the whole false rationale, motives and modus operandi that I'm having issues with.
