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.
