Don't play coy. You know as well as I do that the adjustments make head positioning less critical, but with consistent and correct sight picture you can eliminate the detrimental effects of parallax even without a mechanical adjustment.
Its not "playing coy". You aren't eliminating parallax, you're mitigating it. No matter how perfect your sight picture, it is still there. There is a reason rimfire specific scopes are made, and a reason every rimfire BR shooter uses an AO or SF.
Read what you quoted again. We can debate definitions and semantics all day, but the fact is that with a consistent and centered sight picture, any effects of parallax are eliminated. Mechanically adjusting the focal plane of the reticle simply makes it easier to eliminate those effects by eliminating parallax itself.

There are the definitions. They aren't up for debate. No matter how hard you try, you won't perceive all parallax error on a fixed parallax optic. I've tested it. It even exists with an RDS. The more magnification, the greater the effects.
