Top posting from phone. Making the bind9 libraries private was a deliberate decision by upstream, so there’s no guarantee about API/ABI between patch releases. Keeping the compatibility for isc-dhcp which is basically on life support.
bind-dyndb-ldap is kind of special because it’s the only external dyndb plug-in ever created. We’ve already talked about solutions with bind-dyndb-ldap maintainer that perhaps it should be built as part of src:bind9. Unfortunately, it’s bit of license mess because bind-dyndb-ldap is GPLv2 and BIND 9 is MPL 2 :-(.
