Why make exceptions? Let's keep the rules as simple as possible (but not simpler). Routes are always relations anyway, to allow ways to be part of multiple routes.
Legislating that a motorway_link should never have a ref tag, is a rule which is asking to be broken a million times. I try never to remove (possibly correct) information from OSM. In the absence of guidance from the wiki, what is "correct" is very subjective. I for one will never remove an existing ref tag in order to make the slip road wiki-compliant. If it contains the motorway ref and the wiki says it should be the junction number then I might "correct" it. But it would be a step too far to remove the information, which someone, somewhere may be relying on, without it being available (and supported in tooling) via a different route.
