As long as the upper ACL lines are left in place by the local admin.
Even if the local admin removes the unconditional verification, it is
still important to have local addresses verified to be able to reject
those undeliverable mails at SMTP time.

Yes, but unverifiable local addresses are going to be rejected before
by the ACL stanza you want removed.

Please note that line 349 will reject unverifiable addresses.

The lines are indeed superfluous in the default config, but are there
as a safety measure in case of local modifications to the ACL. This
may be for historical reasons, but changing it now does not affect
functionality, and forces all users to go through a dpkg-conffile
changed dialog. I'd rather avoid that.
