Comment 1 for bug 1899902

Thank you for the report Aristarkh.
It is odd that this was fixed so long ago - 1:9.11.4+dfsg-1 is what the debian bug states.

That was only pushed to Debian buster in:
 195 bind9 (1:9.11.4+dfsg-1) unstable; urgency=medium
 196
 197 [ Bernhard Schmidt ]
 198 * Use systemd Type=forking to signal daemon init.
 199 Thanks to Elie Roudninski (Closes: #900788)

But I don't see it on any path to Debian/sid - not in the past changelogs nor in the currently used .service files.

I need to ask if this might have had an intentional reason ... or if it really was "lost again" later on.
