No, it doesn't.  It requires the decision which modes to use, which is
independent of what XDG mandates.

Done.

Follow-up from "Please document the caching and its user options"
https://yhetil.org/emacs-devel/86le35rwyp.fsf <at> gnu.org/

Currently `xdg-cache-home`, and other functions in xdg.el only return
the path, but never create any directories.

However, to follow XDG spec, XDG directories must follow certain
rules. In particular:

    If, when attempting to write a file, the destination directory is
    non-existent an attempt should be made to create it with permission
    0700. If the destination directory exists already the permissions
    should not be changed.
  https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html

May you please add a functionality to xdg.el to create the directory
with right permissions, so that xdg.el users do not need to know these
technical details of the spec?
