The s-o-b line is about the DCoO, which is given here by both of us,
with the code starting in a shared tree that only had that s-o-b. I
can remove it though if you think it's strange to have two s-o-bs.

I was wondering about the ordering of these, actually. I've seen s-o-b
on top and s-o-b on bottom of the cc list in lots of commits and
haven't yet divined the One True Position.

Yep. All of those ifdefs in this and in the other primitives are
already gone, and everything is fully IS_ENABLEDenabled now.

Already done, per your suggestion a few days ago.
