It should default to a single location maybe a XDG directory instead of polluting every directory

What happens when you edit multiple files from different folders with the same name?

I tell emacs to create all of the files in "~/.backups", and it names them using the full pathname with "/" replaced with "!". So "~/foo/bar.txt" -> "!home!username!foo!bar.txt~"
