Re: [csswg-drafts] [css-borders] Add a 'hairline' border-width value (#3720)

> The use case is not actually "render a border 1 device pixel wide". If you have a thoeretical future screen with 100dppx, you don't want the border that small - it would be practically invisible. The use-case is "render a border thinner than 1px, if it's possible for the screen to do so while maintaining the sharp line we expect from borders".

If that's the use case, isn't it already possible with e.g. `0.5px`? I imagine the answer lies in "while maintaining the sharp line we expect from borders", but I don't see what's not sharp about it.
