@zooko I don’t know you have authority on decision on ASIC Resistance Hard-fork. But, You have technically core influencer I guess.
You spending very important times for fork.
All of consideration come out.
case study #1 : Monero Forks.
case study #2 : BTG hardfork ready action : change params to A(144,5)
case study #3 : ZeroCurrency (fork from Zcash) : changed params to A(192,7) prevent ASIC Well.
So, I think you don’t need to hesitate on hard fork.
As I alreay mentioned strategy, it will make a times to implement for new consensus , what if you think decentralized ideal way. POW+POS hybrid or multi algorithm (GPU + ASIC) or POS .
Zcash company hesitate then loose time to ASIC preventive forks , mining will Shortly ASIC Centralized , Bitmain and Innosilicon has released.
