The worst Tailwind I've seen is HTML littered with a, a:hover etc. declarations on every hyperlink. OK, you can create a global Tailwind stylesheet in your config but doesn't that defeat Tailwind's purpose?
Oh, and that's discounting responsive breakpoints. So if you have 3 of those that can be 3 lots of a, a:hover etc. for every hyperlink. You couldn't make this up.
