It helps the problem by tagging the state of all your random dot files to the same source set. Any that config changes very rarely anyway. Unless you are using super bleeding edge software. Sure you have to change things still but atleast you have a well track set of what you’ve changed how you’ve changed it and what versions it’s all set to. Non-declarative systems mean you still have to do all the updating but now it’s all a much of untracked manual work unless you’re real good at documentation. Hope that helps!
