I wonder how many apps actually read the correct XDG environment variables and obey them, versus just hardcoding paths that match their machine’s config paths (typically ~/.config/*)

I almost want to set up a VM that sets up XDG_CONFIG_HOME as ~/.foobar and see how many apps actually respect it, and how many still write to ~/.config.

I don’t mind ~/.* for config, especially when the config is just one or two files. What I don’t like is programs like go and cargo treating my $HOME as a dumping ground for every file they want to download and/or cache.

I contemplated for years and eventually saw someone implement a transparent kernel redirect for programs reaching for ~/.*
