You're reading bolder claims into the quick contextualization in the preamble than I am.
If I saw an earlier edit of yours correctly, you were using "must" when the article uses the weaker "should". And the article itself later admits "nothing about this technique is unique to quaternions" and compares vs matricies, without framing it as a contradiction of suprise in light of the aforementioned "conventional wisdom".
I read the sentence in question as merely claiming:
1. Conventional wisdom says that you should represent your rotations as quaternions
I would lightly agree with this - granted, for more reasons than just solving gimbal lock (hence why I brought some of them up) - but they're the right default, admittedly sometimes with exceptions.
2. quaternions avoid this [the gimbal lock] problem
And I would lightly agree with this too - with the article pointing out the important caveat that you can't just construct 3 quaternions from your euler angles and assume that will fix your euler angle caused gimbal lock problems. You gotta use 'em right.
-----
We agree that none of the following are true, nor "conventional wisdom":
- quaternions must be used
- quaternions are the exclusive solution to gimbal lock
- the only distinguishing feature of quaternions is their ability to solve gimbal lock
But I don't think the article was claiming any of those things. Perhaps an exhaustive sidebar into the various differences and pros/cons of various rotation methods could have been useful? My two reasons weren't exhaustive either!
... on the other hand, it also might be reasonable to practice restraint - keeping the article focused on a single topic, generalization into N dimensions of solutions to gimbal lock specifically?
Non-exhaustive sidebar?
¯\_(ツ)_/¯
