Not worrying too much doesn't mean not worrying at all! We still have tools in place to ensure silly mistakes aren't made or are at least rectified quickly. Just we don't expect 100% test coverage on every single feature or fix we ship.
This approach will probably change as we get larger but being a small development team means that it is fine for now.
