As MFPA mentioned: This would not prevent mapping. It would (if noone fails) 
help limiting the access to the identities in the map to those who are 
supposed to be able to do that by the decision of the respective identity

The access to signatures is not limited. Everyone decides himself which ones 
he needs. But the owner of the identity decides whom it is revealed to.
