There are more use cases. Example XXVIII shows a quite common
rendering and it's not natural to think of it as "dashes". The
proposed mechanism can be used for many other designs as well so I
think it's better to think of this as clip regions on whatever border
would otherwise be drawn, than as a refinement of the border-style
keywords.

If we were to use your idea of refining the keywords, what would your
properties be?

  dashes-top, dashes-right, dotted-top, dotted-right etc?

And, how would rounded corners be shown?

HR isn't suitable for the original use case; the footnote areas only
exists as an @-rule in the style sheet:

  @footnote {
    margin-top: 0.5em;
    border-top: thin solid black;
    border-parts: 4em;
    padding-top: 0.5em;
  }

... so, there's no place to put the HR element.
