What is being recommend is that no one take calculus in high school.

It’s very commonly taught in 10th grade in France, Germany, Singapore and Taiwan (where I used to teach). It’s not universal by any means but as far as I can tell, the idea that calculus should be delayed until university is a nearly uniquely American idea.

I can’t speak with certainty about other places but this directly contradicts my experience living most of the past 20 years in Taiwan (and speaking with friends who taught mathematics in the public school system).
Many, many people not on a STEM track learn calculus in high school.
