we would also have to forbid sortm. i think that way lies madness, since UID's are often 7 and 8 digit numbers, bad for human consumption.
the earlier suggestion to maintain a mapping between message numbers as seen by the MH toolset and UID's seen by IMAP, makes sense to me. though for Maildir i don't know if there are UID's.
