The above statement turned out to be untrue at the time; fontconfig used
to not honor XDG_DATA_DIRS.  That's now the case with the newest
fontconfig release, if XDG_DATA_DIRS is set (which probably won't -- due
to 22138), Emacs should be able to discover fonts in a different profile
than the user or system profiles.
