Frankly, I'm not against adding it, too, in that form.  But the
documentation should clearly state the limitations (that the return
value of advised functions is not meaningful etc.).

(Personally, I would prefer (min . any) instead of (min . many).  A
function accepts any number of args, min at minimum.  That don't need to
be many).

And I would sleep much better tonight if it would get a name like
"help-function-arity".  I would even try to find a reason to make use of
it in help.el ;-)
