[Grok-dev] Why must a CodeView have a render() method?

I often use views that are not browser pages, i.e. they are not meant to 
be published, but contain utility functions looked up by traversal in 
other contexts (e.g. conditional expressions).

I had thought this was one of the use cases for a 
grokcore.view.CodeView, but I guess not, since it requires a render() 

Would it make sense to either relax this requirement, so that a CodeView 
without a render method can still be looked up but can't be published 
directly? Or maybe to add some other kind of base class for this use case?
