Are features that do not co-occur with the output variable (of a complementary distribution/(-)ve point-wise mutual information) deemed irrelevant?

The fact that a feature is of a complementary distribution does not seem to be a sufficient reason to discard the feature as irrelevant; especially as they seem phenomenologically relevant.
