Sure you can disable them, but if you're going to be using IMAP  
clients to access them the UIDVALIDITY values will change all the time  
which will cause clients to download the messages (or headers at  
least) again every time a mailbox is selected.

You could also store the index files on local disks and preserve  
UIDVALIDITY.
