this doesn't implement anything and you should feel bad

@sambacha it seems you haven't read the PR or the issue, across clients we do not have great standard errors , which means you can't effectively test well across clients. This has hamstrung client devs for years, besu doesn't respond the same as nethermind doesn't respond the same as geth. In fact there aren't even good guidelines on how error codes get expanded. This PR represents a tangible way forward and is not autogen'd or anything, in fact is the culmination of months, and almost a year of work.

This is rude to comment on repos without asking questions about the issue first. If you have a complaint about the PRs or issue, I implore you to synthesize your thoughts or criticisms of it and put that here, but don't try and deter people from even reading the PR or evaluating it on the merits of it's contribution.

Please be respectful of the hardwork people are putting in to make the ecosystem better, for the entire Ethereum ecosystem.
