Or what if you want Maildir INBOX and mbox others? Maildir would support subfolders, so you'd have to include it in the namespace reply at least if it's hierarchy separator is different than with the mboxes.
No-one's supposed to use mbox. Optimize as much as you want, it just doesn't scale at all.
mbox is fine as long as you don't want to delete messages. It's perfect for read-only mailing list archives.
Unless you run incremental backups with systems such as IBM/Tivoli Distributed Storage Manager that save complete files. Switching from mbox to Maildir has a *major* effect on the nightly backup data volume. With many users or users with big mboxes, or even with read-only list archives that include "current month", it's just prohibitively expensive.
I'd let my sister use it on her computer, but not in serious production -- I'd use NNTP to offer read-only archives rather than IMAP, but that's a personal preference.
