You mean you'd prefer the code read

        if (!dom_enabled(...))
                goto drop;

rather than

        if (dom_disabled(...))
                goto drop;

That I could do easily enough, but I'm not really sure I see the
difference.   But if that's what is generally preferred, that's
a truly trivial change (to change just that code style, and nothing else.)

I don't really really want to do

        if (dom_enabled(...)) {
                /* shift right existing code */
        }
  drop:

because some of the insertion points just don't fit that model - in almost
all cases though, the appropriate logic, is "if the domain doesn't exist,
then do the error path".
