I would tend to agree. However, the degree of compatability and the time  
spans in questions are under the development team's control. It may, at  
some point, become more important to ensure continuity than to perfect  
things. Extreme example: In Plone the core Plone product is called  
CMFPlone. It pisses Alexander off. Should we rename it 'Plone' and thus  
break every product that ever imported from CMFPlone? Should we make a  
jungle of aliases and deprecation warnings? Or should we live with our  
mistakes? In this case, the benefit is marginal and the potential  
confusion and breakage is high. That trade-off point moves with time,  
though, as the more major parts of the framework become "right" and as the  
user base increases. However, that same user base will not increase beyond  
those who are so well-informed that they know what they're getting  
themselves into, if the software gets a reputation for breaking your code.

I guess the question is, how far along that curve is Zope 3? How far along  
does it want to be?
