Python package naming: Dots vs hyphens

[pelzflorian (Florian Pelz)]

Shall I rename python-zope-* to python-zope.*?

I am in the process of packaging mailman 3 which according to the pypi
importer needs packages like

python-flufl.bounce
python-flufl.i18n
python-flufl.lock
python-lazr.config
python-lazr.delegates
python-zope.component
python-zope.configuration
python-zope.configuration
python-zope.event
python-zope.interface


However the zope ones have already been added since 2fc5f186801, but
with a hyphen instead of a dot.  Which one is correct?  Shall I rename
python-zope-* to python-zope.*?  Or shall I correct the pypi importer?
Ignore it?

Florian
