The Ethereum ecosystem seems to be gravitating towards 0 miner tips. Geth fixing it's minimum tip enforcement to 1 gwei caused some outrage; blobs do not tip miners at all; and multi-dimentional gas might also not. I'm worried this again favours MEV. https://github.com/ethereum/pm/issues/1043#issuecomment-2112364286

There's no per-blob tip in EIP-4844, but at least my multidimensional gas proposal (EiP-7706) includes a per-gas tip for all three types of gas.

I guess the catch is how to you optimise for multiple tip flavors? At least EVM execution gas is lower than what's requested, so the tip is not guaranteed. It works now because you can greedily select the best. But for multi dimensional tips to work, we need them to be deterministic without needing to run the tx first

Not sure what you mean by "deterministic without needing to run the tx first". In EIP-7706, the per-gas tip for all 3 types of gas is deterministic, you don't need to run the tx for it. The only thing you need to run the tx for, is the added information of how much of the first type of gas (execution) the tx consumes.

I meant that miners would want to prioritise txs with the most cumulative tips across all gas dimensions. The "tip per gas" currently is deterministic, but we don't know how much gas we will end up consuming. With multiple dimensions - if the gas usage is unknown in advance - the sum tip gets hard to optimise for.
