dovecot - May 2020 - Public folder replication ( not replicating) - roadmap query

Hi,

We have a server pair running Dovecot 2.3.10 (latest stable) version 
directly from repo.dovecot.org and have mailbox and sieve replication 
working as required in production.

I have setup a test pair with the exact same configuration and on each 
server setup public name space for a? mailbox address such as jobs@ 
where multiple users would need to subscribe to this to view recruitment 
emails.

This is not replicating as per the advice on the below url:

- https://wiki.dovecot.org/Replication

Is there an easily maintainable workaround at this time and is this on 
the roadmap for the developers, if so what time scale is being envisaged?

Kind regards

Daniel
