Speed.

I tried out SqWebMail (which reads maildirs natively) on my
biggest folder (openbsd-misc, with 25000+ messages in it), and it just
ripped through it while IMP and Mutt were still chewing through headers.

Removing the IMAP layer does mean you lose the meta-information for
each message, like reply-flags and so on, which I didn't like.

Disclaimer:  this was tested when Courier-IMAP was in its infancy,
so performance may have evened out since then.
