You can't really force applications to use attributes. However, you can
store in the package where the application will store its extra files,
and then remove it (if requested, you may want to keep your settings
around sometimes).
That's also a reason why Firefox shouldn't abuse the settings directory
as its cache. That's what B_USER_CACHE_DIRECTORY is for (and that could
be deleted by the package manager automatically always).
