100% coverage doesn't prove the code is fully tested, just like having unit/integration/acceptance/smoke and other types of tests doesn't prove that application works. But this doesn't mean we stop adding tests to our suite, so why stopping adding more coverage? I totally agree with "just stop mocking so much stuff". Most of the time we can use real implementation and by doing this, we'll also increase coverage.
