DLZ deprecation timeline

[Ondřej Surý]

Hi Douglas,

there are no plans to remove DLZ yet. If we ever decide to remove this, we will follow https://gitlab.isc.org/isc-projects/bind9/-/wikis/Policy-for-removing-named.conf-options

This basically means that the earliest date for removal of this feature would be 4+ years in the future, but in this case it is unlikely to happen unless we speak to Samba project and have a clear path for you to go ahead. We are not going to pull the rug from under you.
