 Actually, if you look, the case here is not about origin at all, but about
 the last seen name. So this part of RFC clearly does not apply.

 But I'm adopting the bind9 approach.

 I guess they'll be once the old loader is replaced. But until the loader
 is actually used in something user-visible from outside, then hardly.
