If practical experience is of any relevance:

* Users complained about SmartPtr being bigger than it ought to. That is due
to multiple inheritance. If I understand correctly, a compiler is not
allowed to appy EBO to all base classes in a multiple-inheritance scheme. A
single inheritance solution with nested templates would avoid this problem.

* Users did not complain about SmartPtr being limited, unnecessarily
complex, hard to use, or not validating their designs.
