Stitches css prop support

[zslabs]

👋 I've enjoyed working with Emotion's css prop in the past - and found Stitches variant usage a bit outside of my normal workflow. I noticed that with the Stitches/twin.macro integration, something like this seems to work fine:

const Button: React.FC<ButtonProps> = ({ fullWidth, ...rest }) => {
  return (
    <button
      css={{
        ...tw`relative font-semibold rounded duration-150`,
        ...(fullWidth ? tw`w-full block` : tw`inline-block`)
      }}
      {...rest}
    />
  )
}

Is there any downside to this inline approach? The Next.js example looked to compile fine, but figured I'd check-in on potential drawbacks.
