Just a quick update, I think this is a codecov bug as per here: https://community.codecov.io/t/prs-are-commented-even-with-comment-off/941

The yaml configuration doesn't show up here: https://codecov.io/gh/python/cpython/settings/yaml

While we wait for a response from codecov, we can fix this in the interim by overriding the settings at an organization level. An owner of the Python organization can enable this here: the organization level stuff would be here: https://codecov.io/account/gh/python/yaml

placing

```
comment: off
coverage:
  status:
    changes: off
    project: off
    patch: off
```

as the config should hopefully fix this for now.
