Basically because there are no artificial constraints. The aliases map
is specifically designed for local users and LHS/RHS addresses in it
can't be qualified. Hash, LDAP etc. maps don't have these constraints;
what's more, wild cards are supported. If there's no need to use the
constraints that the /etc/aliases format imposes, I'd rather not use
that format.

Yes. Nothing to stop one using LDAP or MySQL etc. for this, they're all
interchangeable with hash for virtual.
