lgtm, just missing a ts test for this.
An alternative to this would be instantiate CheckEvmTransaction with is_empty result, and make this check be part of validate_in_pool_for. The added benefit of that approach is we do this check when following pallet-ethereum or pallet-evm direct code paths, so sharing behaviour and error handling is ideal.

The EIP-3607 check should be done on the transaction validation (here) andon transaction execution, otherwise a transaction from a contract key will be included in the mempool and pollute the mempool forever.
