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

> represents some fraction of a pixel

Is this fraction left up to the UA to decide?

 - If not, e.g. we define that `hairline` means `border-round(0.1px)`, then it seems like we could just avoid adding `hairline` and let authors use `--hairline: border-round(0.1px)` if they want.
 - If yes, why only add `hairline` to a few properties? Why not make it a unit?
