I'm with the other poster on this. I think there are good analogies to stuff like goodhart's law. At times you do need to reground why you are measuring something. That said, most of these lessons were about making the measurement to improve be more holistic. This is a part of an argument people will often use to talk about why end to end testing is superior to unit testing. It isn't that you don't want the units tested. Nor is it that end to end is easier. Rather, it is harder to focus on an end to end test for the sake of the end to end test. (No panacea, mind.)
