Maybe things changed since I was in high school, but the top 10% of students in a given school used to basically try to take as many AP courses as they could fit into their schedule/handle. 

So while it would be elective, from the perspective of a student trying to get into an ivy league school or honors college where ever couple percentage points in your GPA matter, it'd be very attractive to have another "easy" AP course that you can use to pad your GPA.

I don't think DeSantis wants the best and brightest students to be disproportionately indoctrinated into woke BS.

The funny thing is that the existing AP world, European and US history curriculums already have a strong left leaning bent.

I remember when I took the exams years ago a bunch of essay questions were about the oppression of women and minorities.
