On a component that only needs to be defined once, no big deal. But if you need to add this collection of classes on 20 elements, adding a bunch of Tailwind sounds messy and error prone.
Tweaking Bootstrap here and there sounds a lot better than using 100% tweaks. Tailwind seems like a tweak library. Add 10 tweaks to each element and you start to have a design on your hands. I often question why it exists vs raw CSS.
