The new update is a lower number, this is confusing. I will drop my comments in the other thread.
Has there been any analysis on how much gas this would save in practice? Would be quite easy to simulate the last 3 months of transactions with vs without 7863 and see how much gas would blocks used.
Imo this EIP would be worth considering iff we were to reduce gas used by at least 50%, i.e. 2x in throughput. Otherwise, as others pointed out, the complexity is not worth it when compared to the 10x-100x block size increase we are aiming for the next 5 years.
Where do you see the complexity here?
Clients already pre-warm storage slots today and this EIP would just adjust the pricing to account for that.
The positive impact on gas used depends on the number of blocks we allow storage to remain warm. One could think of having a rolling window of 5-10 blocks for pre-warming. See some initial stats here:
