I think it should be on by default.
The problem is if you have an MUA/MDA retrieving lots of messages
over a potentially slow connection, the mailbox can remain locked
for a very long time for a read-only operation.
Or before when dialups were more common, if the modem disconnected you'd
have to wait several minutes until the previous connection timed out.
Still very common in rural USA. We see occasional pop3 locks that last
hours while someone on a 26.4Kbps connect downloads mail. rfc1939 says
it should be locked. I do understand why it's not default in dovecot
though, since Dovecot is primarily an IMAP server, and the idea of
locking a mailbox for hours is probably a bit repulsive to the
developer. :-)

The problem that requires doing it is basically a client problem.
Namely, some clients may get confused if in the middle of a series
of RETR commands, they get a mailbox locked reply.
This should never happen with Dovecot. But what could happen is that the
message got expunged and the RETR would fail because of that.
