Hi! It would be quite nice to start writing postcss config files with full ESM + TS support since it seems to be becoming standard with most popular tools. As an example, a postcss.config.ts file written as such:

import type { Config } from 'postcss-load-config'

export default {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
} satisfies Config

If it is any help, I noticed Tailwind made some small mention of the libraries they used to handle this in a blog post.

Thanks.
