[Dovecot] problematic ACL with shared folders and maildir

Hello,
Recently we have been asked to deploy some shared imap folders within our
instance of dovecot. However, we ran into a problem with how ACLs are
implemented, and consequences regarding maildir++ mailboxes.
Long story short:
* IMAP clients sees the hierarchy as a tree: sample/1, where 1 is a child of
sample
* on the filesystem, sample/1 is represented as .sample and .sample.1, both on
the same level
This presents a problem: dovecot-acl file meant for sample mailbox does not
apply to mailbox 1. In fact, a user with permissions to create mailboxes
under sample, will not be able to access those mailboxes, once created.
Wonder if anybody has been in a similar predicament, and found a solution. Any
hints would be greatly appreciated.
PS) I'm also documenting this process, maybe others will find it useful:
