I don't think the portable OpenSSH source has any systemd integration,
so that is what you should expect.

--8<-- systemd.service(5)
OPTIONS
..
Type=
..
	Behavior of notify is similar to simple; however, it is expected
	that the daemon sends a notification message via sd_notify(3) or an
	equivalent call when it has finished starting up.

I guess that Oracle has patched sshd to call sd_notify() and thus
introduced dependency on the systemd libraries for sshd. I don't
think that's a good idea at all.

To run upstream OpenSSH-portable set Type=simple and be done with it.
