On the contrary, I don't think people should make wild assumptions about obviously unique (and non-copyable) abilities not being bloodline limits.

Do they honestly have to announce "X......is my bloodline limit" everytime a character shows up with one?
They don't HAVE to, but since it's so rare in the Naruto world, it's to be expected that Kishi will let us know as soon as a new bloodline limit character shows up. That's how it's been so far, at least.
