Aha! I am not the only one ;)

Is this a new 8.3 variable? It doesn't seem to be in my 8.2.10 MELPA
version.

I like your idea. I think you could simplify it to just:
(org-add-link-type
"sec"
(lambda (path)
(org-open-link-from-string (format "[[#%s]]" path)))
(lambda (path desc format)
(cond
((eq format 'latex)
(format "%s~\\ref{%s}" (or desc "Section") path)))))
and refer to [[sec:section-1]] that looks like this below.
** some title
:PROPERTIES:
:CUSTOM_ID: section-1
:END:
