indeed, existing emacs fd.o support in various contexts is generally
optional.

They're overrides not mandatory, the normal circumstance for an app that
follows the spec is falling back to the standard paths. When emacs uses
them, which it may already do in various circumstances, you can see it
does that:
https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/xdg.el#n52
At startup, emacs apparently already uses ~/.config/emacs/ if present
and .emacs and ~/.emacs.d aren't:
https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/startup.el#n494
However, at time of writing a user using the existing emacs xdg
~/.config/emacs/ dir support will AFAICS actually find various arguably
"data" and "cache" files also plonked into the "config" directory
~/.config/emacs/ dir by emacs, as it's basically treated as an
alternatively spelled ~/.emacs.d/
That may be consided at least vaguely suspect under the xdg spec
conventions, user config, cache and data files are supposed to have
those split locations. To concretize, testing with emacs 27.1
(personally I actually still use ~/.emacs and ~/.emacs.d/ normally!):
# keep for restoration!
$ mkdir -p .config/emacs/
$ cp .emacs .config/emacs/init.el
$ mv .emacs .emacs.off
$ mv .emacs.d .emacs.d.off
Run emacs
$ emacs
# intra-emacs do something arguably "cache" and "data" like getting the
# latest elpa package list and installing a package
M-x list-packages
<install something, trie for argument's sake>
C-x C-c
# let's look inside:
ls ~/.config/emacs/
$ ls -1 ~/.config/emacs/
auto-save-list
elpa
init.el
$ ls -1 ~/.config/emacs/elpa/
archives
gnupg
heap-0.5
heap-0.5.signed
queue-0.2
queue-0.2.signed
tNFA-0.1.1
tNFA-0.1.1.signed
trie-0.4
trie-0.4.signed
# -> user ends up with emacs init.el in config (fine), but also
# elpa package lists stored in xdg config subdir not cache
# elpa packages installed in xdg config subdir not data
This contrasts to e.g. python's "pip install --user", as that will
install python packages ~/.local/lib/python3 etc. as "data", and keep
its various transient metadata things in ~/.cache/pip/ as "cache"
