Yeah, me too. Turns out it's not such a hot idea after all. :)
Disk-based products is the way to go (often just called packages in
Zope3).

Yes, that's a good reason to avoid it, because upgrading becomes
problematic. Normally you want one development site and one production
site, and you want to develop the code on the development site and
then move it to the production site. But when the code and the site is
the same, this becomes trickier.
