Re: [csswg-drafts] No way to set the underline width/thickness

I don't see why such a note is needed at all. Specs are primarily read
 by implementors, not authors. Also, authors are pretty familiar with 
em units by now, so I think it's a but superfluous. We don't have such
 a note in `line-height`, `text-indent` or `letter-spacing`, which 
benefit from em units just as much.
