i think what we meant with this bullet was that failing tests in CI shouldn't disable your deploy tools. however, you shouldn't deploy code that changes tests from passing to failing

(i think this is a better policy than "dont deploy code when the tests are failing" since test suites often get left in a failing state and you dont necessarily want to clean them up if the failure is caused by something unrelated to your changes. even though in my ideal world we would never leave test suites in a failing state. thoughts @azylman and @rgarcia?)
