To me this also misses the point. An eierlegende Wollmilchsau in my book represents a non-existent solution to every single problem in a context (or at least too many problems) at the same time. The whole point is that there is no such animal, and this should indirectly indicate that the author thinks this sought solution does not exist – not that it just has not been found yet but that such a solution is impossible, maybe even absurd.
