Well... As can be seen by Gavin's "nagging"* post below, it looks like this issue would not go away after all, eh?... ;-)
* - I'm making use of this adjective here not in a derogatory sense, but to illustrate that until some issues are addressed by the SI system developers they will NOT be able to provide us with satisfying answers! Unfortunately though, m/s would suffer from "application-related" shortcomings, something that apparently can only be reasonably addressed by a unit of the magnitude of km/h (not 'hr', ok, Gavin?...). Evidently, it goes without saying that had time been "metricated" and we wouldn't have such problem, since we'd use a legitimate prefixed unit of time to satisfy such requirement (example: km/ks, or km/h, where hour is "metric hour").
