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

Are you imagining that `border-round(expr)` is semantically equivalent to `max(hairline, round(down, expr, 1dppx))`? My reservation is that by including "border" in the naming it means that any future semantics that get added to painting borders, might inappropriately get conflated here too.

I wouldn't want to inherit disappearing borders from Firefox when the value becomes too small, even if that's correct for borders.
