[Zope] Zclass bug

Hi, Is the Zclass bug going to be fixed in the next release of Zope? The bug I am referring to is the arcane way of having to 'change' a factory when no change has been made when you are creating Zclasses within Zclasses. Or is this already done or perhaps there is another way that fellow Zopists are creating workable Zclasses within Zclasses. TIA, T
