There are people going for 100% coverage and pedantic unit testing so that it only works with that particular implementation they wrote and then when you want to change something, you'll have a pile of tests to change that don't add any value. Something like this we try to get rid of.

Kind of like animations. Mobile apps hide latency by adding transition animations that are longer than the load time.

Also the automated security scans. All new frameworks cover the cases. Real box ticking exercise.

Though I am a TDD fan I understand your point.
