So, in what ways (other than elegance) is @G.Sliepen's answer better? IIANM yours would work with C++14 and and std::experimental::optional, wouldn't it?

You can use the trick of @Deduplicator and write using T = std::common_type_t<Ts...>, so you can drop class T from the template arguments, and then use auto return type.
