when will be QSharedFromThis for QSharedPointer?

[fsmoke]

If someone finishes the patch, including the documentation, gets it past the basic code review process and argues the case for having it in the first place then it may get into a future Qt. Since nobody has touched the bug since 2010 I don't think anyone's need to scratch this itch is strong enough.

But without this functional - Qt shared pointer mechanizm is no full - it's not useful!! I port small tree class from boost to Qt, some like this

class TreeNode
{
public:
void addChild(QSharedPointer<TreeNode> p);
private:
QWeakPointer _parent;
QVector<QSharedPointer<TreeNode>> _childs;
};

inside method addChild(boost realization) new child TreeNode field _parent was assigned to shared_from_this - in Qt realization i can't do this.
Besides TreeNode is parent class to other types and they can add child nodes themself. So I need to rewrite common architecture of my application - I don't want do this.
