Given the prevalence of tailwind in major projects and a technology loved by many, adding direct support for tailwind by Expo would be a massive win and improve cross platform consistency and developer productivity.
Currently, the best know (to me at least) package for native tailwind integration is Nativewind (https://www.nativewind.dev/).
However there has been a long and drawn out delay in the v4 release and I fear the project requires substantially more support, which it is not getting.
Give the ubiquity of tailwind, I believe this feature is becoming a necessity for frontend work.
