It isn’t about having a bad taste from the past. Policy like this would further disenfranchise vulnerable populations present day. A barrier for entry like this is going to disproportionately impact lower income folks. Hard to study for a test like this when you’re busting your ass at 3 part time jobs trying to make ends meet. That’s not even to mention the inequality that exists within the education system between higher and lower income areas to begin with. “Our system failed you, so now you’re not qualified to vote. Cheers!”
Three guesses as to who this policy would affect more: white people or people of color?
