One big drawback of Tailwind I never hear anybody talk about: it makes things all but un-targetable by other CSS.

Say I just used regular CSS. And say, eventually, I need to turn all the section subheads on a page green.

Easy. Just use the `.subhead` class you already wrote to add an override. Done.

In a pure Tailwind world, that doesn't happen. You literally have to edit every single component you already built, because not one of those utility classes is actually unique to those subheads.
