Some points on the EIP:
Why is Glamsterdam Meta EIP a requirement? Does it strictly need Glamsterdam?
Gas amounts
This currently lists regular and blob, but since EIP-8037 (Glamsterdam) now we have execution, state, and blob gas.
Execution block
If there are fields removed then this should be explicitly mentioned. The original fields are: parentHash, uncleHash, coinbase, stateRoot, transactionsRoot, receiptsRoot, logsBloom, difficulty, number, gasLimit, gasUsed, timestamp, extraData, mixHash, nonce, baseFee, withdrawalsHash, blobGasUsed, excessBlobGas, parentBeaconBlockRoot, requestsHash, blockAccessListHash, slotNumber
It seems uncleHash, logsBloom, difficulty, mixHash, nonce, blobGasUsed, excessBlobGas are removed.
The last 2 items are likely meant to be in excess_gas, except this maps to a class with regular/blob fields while the original header fields are blobGasUsed, excessBlobGas. Removing these params means speccing the behavior of the EIP-4844 mechanisms (how to calculate gas price) is part of this EIP.
The items removed should be stated and it should also be motivated why these are removed.
JSON-RPC
What about the removed block header values? What about the methods which query those fields? What should they return?
