I like the idea to put temporary automatically created files to a 
dedicated directory. Backups are easier when hand-written config files 
are separated from stuff that can be recreated on demand. Since enough 
applications follow XDG conventions, I suppose, XDG_CACHE_HOME=~/.cache 
is a reasonable variant consistent with user expectations. Emacs 
directory may be a fallback when XDG_CACHE_HOME can not be created. I am 
against using ~/.cache only if it already exists. It may result in stale 
cache in the emacs directory populated before another application 
created ~/.cache, so user would have 2 directories with cache files.

I agree that xdg.el lacks some useful features. Even parts of emacs such 
as startup.el and files.el do not use this package. Similar libraries 
for other programming languages offer wider support of OSes and create 
directories on demand, e.g. https://github.com/adrg/xdg for Go.

Maybe org-macs.el is a better place for code dealing initialization of 
cache directory.

P.S. `org-open-file' may benefit from using of xdg.el. MIME handlers 
obtained from .desktop files should be more consistent with expectations 
of users of desktop environments.
