Seems so, e.g.

allout-kill-line, allout-yank-pop, dired-do-kill-lines,
doc-view-scroll-up-or-next-page, doc-view-scroll-down-or-previous-page,
follow-scroll-up-arg, .... there are lots of more examples.

The feature we are discussing in this report is also already used, see
`toggle-menu-bar-mode-from-frame' for an example.

Dunno.  OTOH, most commands using the prefix arg don't distinguish
between interactive and noninteractive calls.  Why should
`define-minor-mode' describe the two cases separately?
