Agreed. The OP has already run into this, and disabled some checks;
the logical next step is to stop treating a 10/10 score as mandatory.

Definitely. It's times like this that I'm really annoyed by the abuse
of the name "pep8" to mean the tool, especially since it's not
perfectly matched to the document (notably, it can't encode the
flexibilities, so it comes out as rigid).

Tools like this can be incredibly useful. But they are TOOLS, and the
code belongs to you. They are not your masters.
