'message' can be easily replaced with 'minibuffer-message',
then it doesn't obscure the minibuffer:
(progn
(run-at-time 2 nil (lambda () (minibuffer-message "foo")))
(read-from-minibuffer "Yes? "))
Whereas it obscures the prompt in y-or-n-p:
(progn
(run-at-time 2 nil (lambda () (minibuffer-message "foo")))
(y-or-n-p "Yes? "))

In case of doubt, we could add a new function read-y-or-n-p,
not to replace the implementation of the existing y-or-n-p.
Then like many users already put in init files:
(fset 'yes-or-no-p 'y-or-n-p)
it will be possible to put:
(fset 'yes-or-no-p 'read-y-or-n-p)
(fset 'y-or-n-p 'read-y-or-n-p)
And when it will prove to work better than the current y-or-n-p,
maybe after the next release the implementation of y-or-n-p
could be switched to read-y-or-n-p later.
