I can't give you a general answer other than reading git history, but
regarding your specific options:

 * KeyRegenerationInterval was specific to SSH protocol 1, which you
   almost certainly weren't using and in any case is no longer supported
   in recent versions of OpenSSH.
 * sshd now always behaves as if "UsePrivilegeSeparation sandbox" had
   been set, and this is no longer configurable.

In both cases, you should just remove the options from sshd_config.5.
