I don't see anything in glep 76 about requiring verification of the signatures. It's my view (as trustee) that assertation by the signer that 'this is my signature' is sufficient. Introducing more verification should not be needed. That said I do think switching to a WoT model has some merit, it's just that the name verification is a side benefit, not a primary reason for the switch.

I do wonder about how this part will be enforced. -- Matthew Thode
