The generate_gradle_lockfiles tool has had some good updates recently making it more useful. Recently when @gmackall was updating to AGP 8.1 he had to undo some changes to projects that intentionally used an older version of AGP.

We suggest adding a configuration that lives next to generate_gradle_lockfiles.dart that has paths to ignore by default and to make the tool be able to take a file of paths to ignore so that we can explain why some projects should not have the versions modified.

This would also let us explain if we hit a blocker for some projects that take more work and attach a bug to do the more difficult migrations.
