Yea. To me Tailwind was to make CSS act predictably for someone who was not an expert and just wanted to make some tweaks in a good expertly-crafted CSS theme design without seeing the strangest unexpected things happening layout-wise.
A very large percentage of the Tailwind classes also seem to be more or less 1:1 with CSS, or like 1:2.. So it's the locality and brevity IMHO that contributes most to reducing cognitive load.. Or at least in making it faster..
LLMs get along well with high locality..
I'm not sure if I'm disagreeing or agreeing with you now LOL.
