It's well documented, the link in the OP still works.

IMO a true conversion of Emacs to the XDG spec would involve the
addition of new variables (user-config-directory, user-data-directory,
user-cache-directory, etc). Each use of user-emacs-directory would have
to be reviewed to see where it actually belongs. For some, it would
probably be ambiguous.
