Yes, I think it's very attractive for that reason.

Right. We just need to be crystal-clear in documentation that our 
viewlets are different from Zope 3's regular viewlets in this regard. 
Normally, the rule in Zope 3 is this: if you have a class and an 
associated template, the class's instance is available in the template 
namespace under 'view', no matter what it really is. I realize that the 
idea proposed above is more attractive and I support it, we just need to 
be careful to document it well.
