A nontrivial fraction of people go from one subject in college to a tangentially related career upon graduating. If they had known 2 years later what kind of work they would want to do, then sure. But if you're not willing to give them a shot, you could be missing out on some cheap talent.
(I was an example when I came out of pure math and looked for a programming job back in the 90s, with no programming background.)
If your credentials are worthwhile, that will become obvious. If not, then they don't matter.
For anyone other than recent graduates, I wholeheartedly agree. But for recent graduates, you may have little else to point to.
