I'll trust your judgment on those issues.  But if there are performance
problems with having company-capf in company-backends, it would be very
useful to know it, so please add it by default, so we can fix those
problems (presumably in the respective completion-at-point-functions)
rather than avoid them.

In Emacs-24.4 it should, yes.

AFAIK cfengine's completion support didn't exist before 24.4, so there's
no problem there.
