I was a bit surprised to see zope.interfaces pop up these days. If you are not using the entire Zope Component Architecture I'm not sure how useful it has been since Python 3. Zope and things build on top of it (Plone CMS e.g.) was fairly popular in the early-mid 2000s and was in my opinion ahead of it's time in many ways. But also overkill for most projects.
