Actually, it is mail.local that does the locking, smtpd knows nothing at
all regarding /var/mail as it is an MDA thing.
mailbox locking is complex to be done right with all the NFS horror, and
mail.local, which was already used with Sendmail, solved issue for us so
we decided not to introduce unnecessary bugs :-)

To be honest, after having used wu-imapd and courier, I'd give Dovecot a
go if only because of privileges separation and a more modern design for
such an exposed target.
Also, mbox is really a left-over from the past and unless you are forced
to use it, switching to maildir has many advantages ranging from being a
lock-less delivery method to being easier to manage as an admin.
That being said: no, no, no, * because I'm curious.
