Because we don't test it, so there's no guarantee that it works. In fact, I'd 
be surprised if it works at all. What's more, our types aren't exception-safe, 
even the container types. It's entirely unknown what will happen during a 
stack unwind.

Personally, I don't want to maintain that functionality.

And then there's the question: is it worth the 7% increase in code size?
