The answer depends on several aspects, but in Emacs-25 we added the
prefix-command-echo-keystrokes-functions hook specifically so that C-u
is not so special anymore and other commands can provide the same kind
of functionality (this is used for example in the GNU ELPA package
`other-frame-window' which aims to replace the C-x 4 and C-x 5 prefix
keymaps with prefix commands).
