He did not say that the formatting string is stored with each message; but
there is a requirement that the *UID string* is stored with each message.

i.e. changing the format string does not change the UIDs of existing
messages; or put another way, the format string is only applied the first
time that a new message is seen.

Given that, you could apply *any* UID to messages when you import them, and
the format string will only affect subsequently-delivered messages.
