I find that with the ubiquity of Tailwind, developers treat design as a "solved problem". What's missing is the specific evolution of one's product and the resultant information architecture. The sibling response is my experience as well, design is an incredibly interactive exercise. Granted, not every component on every surface will need this amount of scrutiny. But I'm usually the outlier developer warning teammate…
Even with bootstrap, design was a solved problem. What you bring with a UI designer is appeal (aka make thing pretty and enjoyable). If you want utilitarian, even the old x11 toolkit like Athena, Win 98 era widgets would do the part.
"make things pretty" would be a graphic designer or artist. Are you saying the entire arm of Product design is a made up value?
