I am not convinced that Alt-p and Alt-n are any more widely used than C-p
and C-n, but in any event, it's easy to bind whatever key sequence those
key combinations produce to the same editing functions as C-p and C-n.

I would further argue that the number of people using an emacs minibuffer
to run their shell commands is a small fraction of the total number of
bash users.  The folks doing that are more than capable of adding a key
binding or two.

Because that key sequence is unbound.  Take the key sequence that you see
and bind it to previous-history, e.g.,

"\e[A":previous-history

(where \e is ESC, or meta)
