Because tags like disused=yes conflict with a general principle in OSM: We don't have a fixed set of tags and mappers can invent and use their own tags, so it should be possible for software to ignore tags it doesn't know without causing problems. If I don't support distinguishing between different variants of amenity=parking, I just ignore parking=* tags entirely, and while the result is less useful, it's still correct. If I don't support disused features, I can just ignore disused=yes tags ... no wait, I can't. Of course, in order to make mapping convenient, it's sometimes necessary to break that concept (with access tags, for example), and probably we won't be able to get rid of disused/abandoned/construction/planned/proposed/etc anymore. Unfortunately, people didn't seem to like my status=disused/... proposal very much.
