I don't think this merits 'screw up'. Proxy caching is an optimisation mechanism; most don't support Vary in that they don't cache anything that is content-negotiated. They will still service the request, and indeed handle the Vary header correctly. If a proxy doesn't support Vary in the sense that it will go ahead and cache the entity without considering Vary in the cache key, it's broken. That's their fault, not the content provider's.
