Config files are the lesser problem, although it's really, really, really useful for programs to realize that $XDG_CONFIG_HOME exists.
More importantly, please put your caches under $XDG_CACHE_HOME so they don't trash up my backups or git.
And if you're feeling really fancy, put all your runtime stuff in a separate dir in $XDG_RUNTIME_DIR so /tmp doesn't look like someone detonated a zip bomb in there. I want to use it for my temporary files and still find them, thank you very much.
