Unless you also sacrifice binary compatibility, it's not possible.

What it is possible is to have one allocation instead of 2 (the object 
and its dpointer), that's already been worked upon with a custom 
operator new, check the patches on gerrit.

Anyhow this is entirely orthogonal to the original problem at hand: 
ownership. We need to support the case of objects created on the stack 
(not owned and owned).

Cheers,
