I really like that phrasing. It's quite similar to the improvement we've 
seen in terms of code re-use and manageability in Plone when adapting 
more Zope 3 stuff.

Of course, Grok is less interface-centric than most "plain Zope 3" stuff.

I do think this is a story we should articulate with some well-placed 
examples. For example, when is it worth defining interfaces and 
components explicitly? How are they factored out into separate packages? 
How are these used? Where is the benefit of re-use and pluggability 
being applied?

Excellent. :-)
