This seems not quite right to me. I like the way grok currently does not
enforce a 'main template' onto all views.
I was thinking that skins and layers perhaps should come first. I
haven't attempted any code yet but along the lines of grok/doc/skin*.py
makes sense. (Though I've yet to grasp the distinction between layers
and skins). And thereafter providers can be registered to the skin, and
viewlets to the provider.
Something along the lines of:
class NewsProvider(grok.Provider): # grok.ViewletManager?
and in the skin (or layer?) 'main_template.pt':
<tal:block replace="structure provider:MenuProvider" />
