You may be slightly mistaken about what I am stating: the ambiguity is in the official definition even if it a sensible sounding one whereas the conventional definition is well-defined (‘no first-order consumption’) but arbitrary. The problem arises not so much from arbitrariness in and of itself, but rather demanding strict adherence to (and unwarranted focus on) something that isn’t well-justified to begin with. That leads to all sorts of contradictions.
On the second point, I agree that the distinctions between the two examples are somewhat arbitrary. One may argue that perhaps animal-testing in many instances is unnecessary (turns out several are based on methods and assumptions that have been around for a century and have persisted more out of inertia despite no clear evaluation of their effectiveness) but conventional agriculture depends on pesticides but I wouldn’t find that argument very convincing.
