Major Description
= Why
When listing paths (IMAP LIST, JMAP Mailbox/get) the list of mailboxes is retrieved first, then each mailbox is individualy read in order to retrieve the UID_VALIDITY (part of the mailbox table but not the mailboxpath table).
Given that mailbox read repairs are proposed in JAMES-3407, we can safely skip the mailbox read, if the mailboxpath table holds also the UID_VALIDITY information.
= How
Design a newer version of the mailboxpath table holding the UID_VALIDITY information.
Design a migration to this new table model.
This is exactly what https://github.com/linagora/james-project/pull/3635 proposes
