Every graphic designer I've worked with wants it to be pixel perfect. I've seen them numerous times pull out rulers and literally measure the spacing on their monitor! It takes a special breed to be a graphic designer. In my experience, suggesting that it can be a little off gets me a withering look and the suggestion that maybe we should have another developer look at it. It's never an issue with their OCD.
For some elements of the UI, sure. For others, especially branding related, no, pixel perfect is important.
Additionally, this is a good example of the tooling overstepping bounds. Developers giving feedback that their tooling can't match designs made to fit existing brand standards is naive and doesn't reflect business reality.
As a counterpoint though, I definitely see merit in Tailwind for new web-first applications where the development team can align with designers from the outset.
