'use any unit "as long as they label it" ' seems to be in line with (some people's) philosophy of tagging - use any tag you like, and it'll eventually converge to some kind of concensus. Indeed, that being the case, people *will* and probably *have already* put units into these kind of tags, so chances are units are defacto part of OSM tags. If CSS can do it, I don't see why OSM can't get to grips with units. It's not hard to process a unit string after a number. And there's no reason why such processors can't recognise variations either: km/h, kmh-1, kph; mph m.p.h. etc. because if there is no syntax check you can be sure every variation you can think of and many you can't will arise.
