closing for now then @dmarzzz , this pr can be reopened if in the future if it becomes relevant again

we went ahead and optimistically implemented this. so, every op-reth node is being built with `'opel': [eip-2124-fork-id]` kv-pair in its ENR

> cc @MSilb7 @sebastianst should we still consider this PR? it has been merged to impl, so it seems we must https://github.com/ethereum-optimism/optimism/blob/6d9d43cb6f2721c9638be9fe11d261c0602beb54/packages/contracts-bedrock/src/L2/GasPriceOracle.sol#L236-L250

this involves a maili change after it's spec'd right @refcell ?

> The span batch spec mentions a [v2](https://github.com/ethereum-optimism/specs/blob/afadeea642d05eda6e111d9098c9a842c2ecf322/specs/protocol/delta/span-batches.md#future-batch-format-extension), we should consider adding EIP-7702 support to span batches v2. ~~wouldn't that be v3 @tynes ?~~ ah no it would be like...

as far as specs are concerned, the action items are: - move the previously experimental v2 span batch format up under main heading https://github.com/ethereum-optimism/specs/blob/afadeea642d05eda6e111d9098c9a842c2ecf322/specs/protocol/delta/span-batches.md#span-batch-format - move v1 span batch format...

closing until further notice since is superseded by https://github.com/ethereum-optimism/specs/issues/510, will re-open if eip-2935 doesn't deliver satisfactory performance improvements

need any help here addressing review @miltonjonat ?
