You still need in some sense one coherent file system to store and retrieve
the mail messages. Although a load-balance cluster would still be quite
useful for rejecting the bulk of unauthorized connections.
I am sure in many cases a small/medium server can in fact sit and function
quite adequately behind a large enterprise load balancing firewall and
proxy, given the typical quantities of spam "out there" and the large
number of bad connections typically attempted on any given system.

Director is used when you setup frontend servers in a
load-balance cluster, proxy imap/pop3/lmtp/managesieve requests
to backend Dovecot servers.
I setup load-balance cluster for clients with HAProxy +
KeepAlived + Dovecot Director running in frontend servers, so
sad we have to find an alternative to replace Director in such
case.
It's not about "small/medium" servers, but the demand of
imap/pop3/lmtp proxy service, especially in load-balance
cluster.
