That's gonna be incredibly slow on most developer machines. node_modules, __pycache__, Cargo target/ folders, Yocto build folders, .git folders, etc etc etc -- all my machines which are ever used for development end up with such a gargantuan amount of small files across the filesystem that any operation which involves iterating through all of them takes forever.

Besides, there are .DS_Store I really don't wanna delete. Notably, there are git repos which have erroneously committed .DS_Store files; I don't wanna make those repos dirty by deleting them.
