Hmm, there seems to be a third way that some packages use:

3. declare your egg to be a 'Products' namespace package, omit any
entrypoint or registerPackage declarations and rely upon setuptools
splicing you into the Products.__path__ list and being found the
conventional way of scanning the (virtual) Products namespace.

BTW, I'm working with Zope 2.12.10, and I'm not finding -any- code that
searches for a zope2.initialize or zope2.products entrypoint - seems to
be a NOP.
