So:

delete foo;

is not conscious misuse, but

delete &foo;

is conscious misuse?  Really?  I would say both are conscious misuse, since

I think Boost can assume that the user isn't going to do random things with
a pointer returned by an API.  That being said, we are better off returning
a type which only allows desired operations.
