Doesn't sound very good to me, adding nodes to existing ways just to import height... I'd rather have the height as a separate info. Much like a road that enters a forest; I don't put a node at that point just to say that this node represents the road entering the forest - I just model the forest as an extra entity and whoever needs to can compute the point. Also, having SRTM data as nodes in OSM touches on the often discussed topic of immutable data. Would it be ok for people to edit individual SRTM nodes? I'd also recommend to first do an analysis about the impact on OSM altogether, i.e. by how much would the planet file grow by importing SRTM data like you suggest? If renderers would start to use that information, then we'd suddenly have not a single "empty" tile anymore, every land tile on the planet would have information on it (right?), how would taht impact storage requirements for tile servers etc.? - Not saying that any of these could be a show-stopper, it's just that such an analysis should be part of the plan.
