Be careful that coverage is a proxy metric to good tests. Striving for high coverage can mislead you on the quality of your tests.

On the flip side, encouraging good coverage usually ends up uncovering some bugs that might otherwise have gone unnoticed until they bit someone.

On the other flip side it encourages writing test that have zero business value.

High coverage is necessary but not sufficient, sure. I don't think you can have a good test suite with low coverage (< 80%).
