Absolutely. The article itself (it's a short one) talks about doing just enough tests to have confidence in a product, and I think that's fantastic for early phase development.

But when changes can come from anywhere (lots of developers potentially making changes) and the need for changes can be urgent, there's a great deal of value in complete code coverage.

Not every developer thinks the same or has the same tendency for errors. I would caution people against thinking about tests as personal verification. With any luck, you'll be handing off that code base to someone else in time.
