Additional note:

At present, yes-or-no-p calls y-or-n-p from within the C layer if
use-short-answers is turned on; this feels convoluted.

Worse the implementation of y-or-n-p  also feels fairly round-about --
perhaps use-short-answers could be handled   in either C or in elisp,
but calling back and forth feels  fragile.
