...and let the search engines write ALL of the serps snippets for your pages? Why?

Well they may not, it's not what we like to see but what is really happening. You may want to do that too (for testing or document prepublish), it basically tells you when the page is listed how SEs perceive its content, title etc, when the HTML head is pretty much empty. They will give it a title and summary.
