1. I stopped "dovecot".

2. I did a ZFS snapshot (play safe!), and disabled incoming messages.

3. I deleted ALL "dovecot.index.cache" (one per mailbox, I have about
500 mailboxes) without any apparent effect.

4. I started dovecot.

5. I moved around with apparently no side-effects. Cache are recreated,
small size, growing as you download messages.

I still would love an authoritative answer.
