Love the I've seen things you people wouldn't believe tone of that last bit. _"I wonder if acknowledgement of that difference leads developers to pick different tools to help them manage their CSS"_ yes, this, I think. I've landed on components have their own classes but to share styling across apps I use components or css functions/variables, this has been the best balance for the designs I work with, since they tend to treat most elements as a 'bag of reused styles with some custom padding' most of the time, where reused styles are more custom than tailwind but not generic enough to make higher order components.
