Well, I would say it's acceptable that the QVariant contain different numeric 
types as the engine changes. Maybe you originally only had double and now you 
have double and int. That would be an acceptable behaviour change.

Changing from void* to nullptr is unexpected, but it does fall into the same 
bucket. The problem is that you can't write code to adapt to it without 
#ifdef, so there's no way to write forward compatibility.

Can we compromise and you delay this change for one release?
