This, and the link you provided, are only valid for Linux,
unfortunately (I wish Solaris was a bit more modern in this regard,
but then again it has a lot of inertia).

Solaris:

cat /etc/init.d/* | grep stop | wc
     152     743    4278
cat /etc/init.d/* | grep start | wc
     212    1222    7444
cat /etc/init.d/* | grep status | wc
      16      89     573

I didn't refine the grep like you did, since obviously there's an
order of magnitude difference (most of the 'status' was from 3rd
party software, not Solaris stock startup scripts).  I would guess
other Unices are just as bad.

Anyhow, Mark, is there any chance that cfengine will support
startup/shutdown scripts as an option to processes: entries or are
we just running our mouths?  So far 3 people have expressed
interest in the feature.
