It doesn't really make a practical difference whether you write an old-
school Product or a Python package, except that with a Product, you
get a few things for free:
* configure.zcml, meta.zcml, overrides.zcml are automatically loaded
* your package is automatically registered in the "Products" registry
You can achieve the same things with regular Python packages, you'll
just have to do it manually in two lines of ZCML.

I would think so, since that's me :)

I'm not sure what the point is you're trying to make. We don't need
Grok bolted on Zope 2 to fill that niche. If people want Grok for what
it is, they shouldn't care that it uses Zope3 underneath and not Zope 2.
