this shouldn't be in the trait imo. if it is, then with attribute #[cfg(test)] or #[cfg(feature = test-util], but that would change the logic here, but this is a refactor pr, so leave it out, just move it to the EcdsaSignature impl body.

please add these as trait methods too, they make sense in reth integration

| fn decode_rlp_vrs(buf: &mut &[u8]) -> Result<Self, alloy_rlp::Error> | ||

this for example can have a default impl, since the trait method Signature::from_rs_and_parity is accessible

should be enough to do

on second thought, would be cool to move all the feature gated methods into their respective XSuperSig trait actually

I thought that too! However, I took iterative approach and decided to implement it in the future commits to this PR. I just did not expect you to review it since I did not ping you. Anyway, thanks for valuable suggestions!
