Thank you for your engagement. I changed your previous account’s trust level, so you should be able to post more now.
Regarding expressiveness: we can not allow reverting at this level. That would require adding validators and block proposals, basically copying Ethereum infrastructure. We want to keep transaction ordering on a protocol level. Therefore, FBA-FCFS (or any other mechanism) you’re proposing would also be all-pay-auction. Regardless of this (implementation) point, I think all-pay-auctions on average do not cause extra waste, compared to only winner pays auction, but we need to check it formally. I wrote about it informally above.
Regarding second row: we chose 500ms for this reason, for it to be low enough, not to make UX much worse, which I think it gives yellow status. If we could increase delay g even further, then 1st row for Time Boost would become greener. So there is a tradeoff here. We have actually studied this tradeoff formally, in the equilibrium, concluding that increasing g (to infinity) decreases investment in latency advantage (to zero), and for a fixed latency cost function, we can exactly pin down the speed of convergence of latency investment.
