Here's why not - I already know that Google will completely ignore the meta description and replace it with their own snippet under certain conditions and queries. I also know that URLs can rank #1 without any meta description at all.
So that, for me, means that the spokespeople at Google have been telling it straight. Now I'm not so foolish as to ignore good data if someone has it. But in this case, I'm using my resources in other directions.
