Samba's AD DC has required the use of the in-database DNS servers (internal or BIND9_DLZ) for some time, but we have kept this option to try and make using BIND9_FLATFILE automatic as well.
We should deprecate this in Samba 4.11 so we can remove it in master.
It will still be possible to use a text based zone file, but such sites will need to maintain the list of DCs able to update any record (or more likely directly update the DC DNS names) manually.
The full removal is in a gitlab MR here: https://gitlab.com/samba-team/samba/merge_requests/614
