so core devs control all the nodes and miners now

Core devs control the code that ~85% of the network nodes elect to run. This is presently Bitcoin's greatest point of centralization.
Right. So it wouldn't be unreasonable that Gavin would would ask for "only" 75% consensus to offset the status quo bias.
At least in my opinion.
Your opinion is completely wrong. Organofcorti exhaustively demonstrated why (given the presence of spoofed nodes) 75% is the most unreasonable, optimally bad number possible.
And why are you still pretending XT/101 has any chance of happening? 101 is the 'red uniform' BIP. It's dead, Jim.
