Yes. In fact, if one exists, it's automatically put on your PYTHONPATH
for that instance. I think we should make Zope 2.8+ instance skeleta
grow a lib/python directory. This can hardly be considered a feature, so
we should be able to sneak it into the next bugfix releases of 2.8 and 2.9.

Yeah, lib/python is a bit more normal (though it adds that extra path
element which feels like clutter). Plus, your suggestion with a
two-faced Products (once a PYTHONPATH container, once a top-level
package) would make everything a bit ambiguous.

Also, Products sort of acts as a namespace package. When we move to
top-level packages, people might want to choose different namespace
packages (e.g. Plone would hopefully choose 'plone' instead of
'CMFPlone' and the CMF might regroup everything under 'cmf', e.g.
'cmf.core', 'cmf.default', etc.)
