Agreed. I would rather have 5% test coverage that checks against all risky edge cases/inputs than 100% test coverage that checks against arbitrary, low-risk inp

Agreed. I would rather have 5% test coverage that checks against all risky edge cases/inputs than 100% test coverage that checks against arbitrary, low-risk inputs. Writing tests to confirm the simplest, most predictable use cases is a waste of time - Those cases can be figured out very quickly without automated testing because they are trivial to reproduce manually.
