I've pushed this to master. In NEWS.28, we have

--8<---------------cut here---------------start------------->8---
** 'yes-or-no-p' and 'y-or-n-p' PROMPT parameter no longer needs trailing space.
In other words, the prompt can now end with "?" instead of "? ".  This
has been the case since Emacs 24.4 but was not announced or documented
until now.  (Checkdoc has also been updated to accept this convention.)
--8<---------------cut here---------------end--------------->8---

So this is the intended bahavior, and the patch is just a bug fix.

Closing this report.

Best regards, Michael.
