From what I understand, the warning removed in this PR was incorrect. There shouldn't be any conflict between osConfig.nix.gc and programs.nh.clean as our home-manager service only cleans user profiles (which nix-collect-garbage does not do). In this scenario they should both work at the same time as they are cleaning two different things.
