Interesting. It looks like the whole macOS preference settings acquisition code 
was taken from Emacs in that commit, including a lisp function written in C: 
mac-get-preference. That was quite a radical commit...

(shell-command "defaults read -g AppleLocale") seems to do the job well, 
although it may not be considered super elegant.

(side note: le Elisp Reference index does not seem to have an entry for 
"shell-command" although "read-shell-command" that is also defined in simple.el 
is there.)
