Hi Phillip, Thank you for your feedback on my patch. I appreciate your insights regarding the decision not to support a default file for the --ignore-revs-file feature and the concerns related to ignoring "cleanup" commits that could potentially introduce bugs. I understand that addressing these concerns is crucial. Specifically, I will focus on: 1. Ensuring there’s a clear and easy way for users to opt out or override the default behavior of ignoring certain commits, especially if they suspect those commits might contain bugs. 2. Investigating how this new feature could interact with existing configuration options that allow users to specify what should be ignored manually. I will take these points into consideration as I work on my changes and come up with a solution to address these concerns. Thank you again for your guidance, and I look forward to your continued feedback!
