Fair enough. It seems to several people, though, that explaining to
people how Python packages are installed and then how you hook up these
packages into your instances is easier than explaining all the magic
that revolves around Products to them. Because in the end you won't have
to explain how to install Python packages at all because it's the same
all the time...
As somebody who's somewhat involved in Zope documentation, I am one of
those above mentioned people.

Given Plone hasn't adopted time-based releases yet, I'm not sure. AFAIK
they want time-based releases, 6 months apart like Zope. Just yesterday
I suggested they make them 3 months off to the Zope releases. That way
they can keep on track with Zope releases and not lag behind all the time.

I let Rocky take this one.
I don't really feel strongly about having this available in Zope 2.8.
