For Ethrex, most of this file are some things I had to pull since they live in crates that have complicated dependencies like network ones (since they live in the EngineAPI crate). The same happen with methods that you see here.
I think the goal is to ask the Ethrex team to move these types into their codebase to nicier crates, with that we can nuke this module entirely and rely directly on them eventually.
For Reth there is a similar situation, but had to only pull one method -- I'll create a comment there.
