Well, it can’t help random spamming, but home-manager actually can help here! You can have a declarative config for your home dir and it will symlink config files into your .config folder. Also, it will by default never overwrite any file, but it will ask you to remove spammed configs over which you want to use your own, and since these are symlinks, they are read-only so no program will change them (which is good and bad, because it means programs can’t be configured through their gui settings for example)
