Landscape.io complains about inheriting from zope.interface.Interface

I have noticed some Plone packages use landscape.io to check the code quality.

So I decided to use it, and there is something I don't get about zope.interface.Interface.
Usally when we create an interface, we derived from it, and that's fine.

Here for instance:
https://landscape.io/github/plone/plone.app.contenttypes/64/modules/plone/app/contenttypes/migration/browser.py#L322
it is not marked as an error.

But in my packages, I get errors, example:
https://landscape.io/github/plomino/rapido.core/3/modules/rapido/core/interfaces.py#L4
"Inheriting 'Interface', which is not a class."

Is there any config to do somewhere so Landscape.io does not complain about it?

Yes, there is:
