Windows actually has the same dotfile infestation problem these days. I mean, you still get stuff in Documents that shouldn't be there, but on top of that you get apps - often Unix ports - that believe that %USERPROFILE% (i.e. one folder above Documents) is the appropriate place for their configs and such (it's not - that should also go into AppData\Local or \Roaming as needed). And they usually use a dot-prefixed name, just because.

I just looked at my Win10 profile dir, and it has 36 dot-prefixed folders, and 7 more files on top level. Offenders include .gitconfig, .rustup, and .vscode, just to name a few.
