@mnabian - not sure whether I should add the changes to the CHANGELOG.md, being just a small refactor. Perhaps after review? :)

[DavidLandup0]

@mnabian gentle ping - any other changes required for the refactor?

Hi @DavidLandup0 , thanks for your PR! We will merge this PR soon closer to the Modulus release in June.

Hi @DavidLandup0 , we have made extensive changes to the CorrDiff code and also refactored the configs. Unfortunately, your changes are not consistent with the way configs are currently handled, and we have to close this PR. We really appreciate your contribution and look forward to your future contributions!
