> hearing the lesson and blabbing it back until one has memorized it fully is a pretty engaging and even "gamified" activity, especially wrt. the most marginalized and disadvantaged students

There are many kinds of marginalized and disadvantaged people and many require the opposite approach. I was very smart but had severe ADHD, was noticeably autistic, and my parents were poor at the time. Most of my normal public school classes were nothing more than repetition, rote memorization, and parroting back answers, no critical thought or deeper understanding of the concepts was expected. That was not engaging. That style of "education" had me failing classes and hating every waking moment of school. It was only the last year of HS that I started to shine after hitting AP classes with more interesting topics that required some deeper understanding and mastery. If I hadn't experienced non-rote classes my last year I might be a janitor now.

Doesn't that directly support my point? The school system ends up relying on rote memorization even when it pretends to be all about having the students learn by themselves and exert critical thinking and open inquiry, as advocated for by the most "Progressive" educators! Isn't it then worth it to just get the rote learning part done with in the easiest, quickest and most effective way, by employing the structured approaches that are ignored by most teachers today?
