Huh? Who says that zope.app.form can have the only definition of what widgets 
and forms mean? So the ToscaWidget guys should have really used a different 
name for widgets, because they do not fuilfill that API? And even closer to 
home, formlib should not have used the term "form" in their library name 
because it is not compatibly with zope.app.form?

Widgets and forms are generic terms for a UI/programming patterns. I have 
never claimed that z3c.form would be backward compatible to any older APIs. 
The main goal of z3c.form is to support some advanced use cases and fix 
design defficiencies of the old API, for example the "update/render bug". 
Further, Roger and I find it to be a security hole that so many 
presentation-related components are callable, because that makes them often 
available via public URLs when not desired.

No, all my writing energy goes into writing doctests these days. :-( I always 
tell myself I should blog, but I cannot get myself to do it. I already do not 
even have enough energy to get involved in most zope3-dev discussions.
