That I can agree with, but this goes back to the suggestion of our own smart 
QObject pointer classes. In non-compatibility mode, a function that adopts the 
passed object should only accept from another smart pointer. If you pass a 
naked pointer, it should reject and force you to clearly state that you know 
what you're doing.
