That's exactly what happens today with the constructors that only take
a std::string, so it wouldn't be any worse than what we have now,
would it?

OK, let's wait and decide how we want to do it properly in stage 1.
(If we're going to make various changes that impact the ABI during the
next stage 1 we might even want to consider changing the
std::exception base class to store something like a
std::shared_ptr<std::string> so that copying an exception object will
never throw an exception, which is something I've been thinking about
recently.)
