Actually its up to the implementation to decide. There are some mailbox formats that cannot support meta-data like UIDs. Servers using those formats have no option but to ensure that UIDVALIDITY always changes so that clients cannot attempt any synchronisation with them, as they could otherwise end up sync'ing the wrong messages. If the mailbox formats does support persistent UIDs then the server should keep UIDVALIDITY constant for as long as it can within normal constraints.
