Your arguing pretends that somebody is to be fooled. That is not the case. 
Nothing prevents gnupg (and I even suggested to do that) from warning that 
this feature seems to just be used for an email address which is does not make 
sense to be used with (for the reason you explained very convincingly).

When offering this feature it should be clearly said that it not worth much 
for most existing addresses. It isn't, too, for new addresses which are 
simple. As a user you should decide to take both or none: a safe email address 
and a safe UID or a normal address and a normal UID.

This would not be snake oil. But a tool that requires certain knowledge and 
awareness. Just as today's gnupg itself.
