IMO, when we use git-blame to find out who is response for specified code, w/o
mailmap we may just found old obsolete email address in the related commit; even
we can search full name for his/her new email address, how can we make sure they
are the same person... so anyway, it can help to find last valid/canonical email
address of someone.
