It's a Gentoo-ism. It's for the (highly unlikely) case of you having
your sshd_config file in a directory different from /etc/ssh, and to
pass other arguments to the sshd daemon.

It's completely redundant and innecessary, but it was the way
different distros dealed with the shortcomings of SysV (OpenRC, the
Gentoo init systems, works on top of SysV).

All of them :D Of course they are overwritten with ._cfg000* backups,
but anyway is ridiculous. As you say, the only config sshd would need
to look for should be in /etc/ssh. With systemd, there is no need for
a /etc/conf.d (or /etc/sysconfig) dir.
