Use cases don't matter. What matters is: is it proper for Variant to 
call the postblit (as it does currently) without regard for the qualifiers?

However, I have found a better way to call postblit that involves the 
qualifiers than the way Variant currently does it. I'm going to submit a 
PR to fix these issues.
