LGTM, just a few nits, but I don't understand which spec update is implemented. The one linked doesn't have TARGET parameter and is tied with EIP7594 rather than ELECTRA

Per my understanding peerDas will use a similar approach (via EIP7594 postfix) but we will do a similar thing for ELECTRA too (this PR is anticipating it essentially)
