Bug#1010606: openssh-server: Include directive not present in sshd_config despite claimed version

Package: openssh-server
Version: 1:7.9p1-10+deb10u2
Severity: normal

Dear Maintainer,


I included an Include directive in my /etc/sshd_config and sshd said it was not
recognised. Indeed, the manual of the installed version does not mention it.
However, ssh -V says that version is 7.9p1 (consistent with apt list openssh-
server), and the release notes for version 7.3 of OpenSSH mention the addition
of the Include directive.

I would have expected version 7.9 to have it as well. Was it advertently
removed by Debian ?
