I’ve given my thoughts on FOCIL quite publicly in a number of different places.
My point remains the same every time: FOCIL is by far the most important undelivered EIP and should have shipped earlier. Builders are inherently centralized, builder censorship is not a theoretical attack, Ethereum has been attacked by censoring builders. Given that code is law and we did not slash censoring builders, FOCIL is the mechanism we need to solve this problem.
FOCIL is special. It is also unironically different thanks to its importance. Nobody cares if the next fork is delayed by six months if they are censored from using Ethereum in the first place.
