[Dovecot] POP3 UIDLs with virtual INBOX and migration from maildir->mdbox

Considering the scenario, where you have some old account with a 
different POP3 UIDL format and you migrate them to dovecot.

So these old UIDLs would be saved to dovecot-uidlist.

At some later time you want to introduce a virtual POP3 INBOX like 
described on:

So you decide to make the new UIDL format "%f" - to make them unique 
across folders.

So far so good.

But then you decide to migrate to mdbox with all your old UIDLs.
The docs says that saving old UIDLs is only supported in Maildir and 
that %f is only supported in Maildir.

So is this at all possible?

Would pop3_uidl_format = %g solve this (except for the old legacy UIDL's) ?
