I believe that is_polymorphic<some_union>::value should evaluate to
false, since unions can't be polymorphic.
Sure, but if we don't have a way to reliably distinguish unions from classes, we're out of luck because there's no way to make is_polymorphic do something special for unions.
We could put in the test for is_union and then ask users to specialize is_union<U> for their unions U until they get compiler support for that type trait.

I thought that would be the case, ie, no way to distinguish betwen a union and a class... but it seems good enough, considering that unions are rarely used anyway.
