Where you move from ZClasses is entirely up to you, of course.

What you're seeing is probably unrelated to whatever "fix" there is in  
Zope 2.9.8. Even if you could prove that this is a new (or old  
unfixed) bug you will probably have a hard time finding anyone fixing  
it, because it's a bug in dead technology that no one wants to support
