This is the point. Every person using OpenPGP needs to make their own decisions about what constitutes an acceptable level of certainty that the person who's identity is being verified and checked against the UIDs on his purported key are valid.

Even if OpenPGP were not silent on this matter. You would still need to know how someone (even someone you know very well) verifies another person's identity and keys.  Assumptions are for fools.  You can't blindly believe that the verifying individual is doing it "right".
