One could indeed argue that the wording in RFC8200 could have been
better. However, the intent is clear, and also since RFC8200 does not
specify any routing header type, in the context of RFC8200 packets
there's no possible destination other than the ultimate destination.

Maybe an errata is warranted.

Thanks,
