Well, as a user for rendering/phyiscs at least I started to like the use quaternions instead of vectors because some operations are just plainly easier and can remove the need to apply them in a certain order compared to vectors. This is from practical experience when the heavy math is abstrated away.
Numerical math was scrapped in my naive CS math curiculum, but I think some operations here have a greater numerical stability for practical purposes.
Heavily reminds me of the pi/tau debate, or proponents of the dozenal system. This is what professinal attachment can do to you.

Somewhat off topic, but the quote from the article "Professor Parkinson actually apologized for not giving me a top grade on it, explaining that he had a strict rule never to give a top grade to a Sufficiency that took more than the basic half-semester." is something that I disagree with it.
I find that applying strict rules to assignments without flexibility is essentially academic laziness (and I say that as an academic) . It tells students formalities are more important than content. While I recognize that sticking to deadlines is important, we should have enough flexibility in our rules to make exceptions. If the teacher apologises for his strict rules, it is clearly a case where flexibility should be applied.
