I think the point is that vc-rcs.el defines vc-rcs-checkin-switches (and
-checkout-) but doesn't reference them.  So the obvious fix is to
replace references to vc-checkin-switches with vc-rcs-checkin-switches
(and -checkout-), in vc-rcs.el.

I don't know how a backend-independent switch could be useful anyway,
but if it is, they could both be used:

  (let ((switches (append (if (stringp vc-checkin-switches)
                              (list vc-checkin-switches)
                            vc-checkin-switches)
                          (if (stringp vc-rcs-checkin-switches)
                              (list vc-rcs-checkin-switches)
                            vc-rcs-checkin-switches)))
