The patch adds to new commands to rc(8). This is what can be done with it:
$ service sshd describe
Secure Shell Daemon
$ service sshd extracommands
configtest keygen reload
It also adds a "descr" variable to sshd's rc script and documents the additional rc options. See https://phabric.freebsd.org/D451 how to print them using service(8).

A first draft of descriptions for most rc scripts in /etc/rc.d
Some could be worded better, some have only "XXX" set.
Over to maintainers.
