It is a very strange assumption that only such things should be certified that 
can be "verified". The certifier makes a statement. This is

a) "I have seen a passport or similar document and compared that to the person 
I met"


b) "The person I met has claimed that the mainkey of this certificate is used 
in a secure offline environment only"

What makes the one statement better than the other? You usually cannot prove 
that a certain person has shown you a certain passport-like document. And 
without a manual signature you cannot even prove that the person has claimed 
that a certain key belongs to him or her.

The WoT will stay close to useless if we do not get a system for certifying 
such status information. And what do you lose if someone does not certify this 
UID? Nothing. On the other hand many people who were not aware of the feature 
learn that there is something called an "offline mainkey" and thus may learn 
something very important about crypto keys.

For that problem the local signature (lsign) was invented.

I set as the preferred keyserver for all keys which 
I create or help create. Why should that be a problem? Because we don't know 
whether some technical failure may occur?
