And if for some reason that's not feasible, the defaults which are
documented in the current man pages
(https://man.openbsd.org/ssh_config,
https://man.openbsd.org/sshd_config) represent the developers' current
opinion of best practice, so you could use the intersection of those
and what you version supports.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
