1) My heart goes out to you here. I feel like re-adapting any existing styles to work in or with a new system can be a real challenge, and I'd hate to have to make it work. I've tried this once in an environment where it would have to mesh into a larger system with prefixes/important. I gave up and wrote vanilla. Tailwind just doesn't seem like a good fit there.

2) They have a couple of pseudo-selectors but just largely don't use them if we need the cascade. We just write vanilla instead, but it's funny how often that isn't required. When things need to be dynamic we'll often use the classnames library.

3) This is really interesting because we haven't really experienced this. I wonder if it's framework or ecosystem specific. I often find opinions vary broadly across these lines because of what you noted about the variance in dev flow.
