The only issue with this is your type may not be allocated with new and you
may want a custom deleter (you may also want to take control from a
separately allocated object). These are things that shared_ptr can handle,
but with a strict interface such as this, the non-null ptr cannot. That
said, I personally don't care, but if the intent is to just have a non-null
shared_ptr then we shouldn't be sacrificing existing functionality. It
should simply be a shared_ptr with a non-null invariant and that is that.
