Reuse of properties is good, in principle. However, I don't think the
currently proposed properties [1] are redundant. For example, to flow
the content of an element into two colums with a gap and a border
between them, you can say:

  P {
    column-count: 2;
    column-gap: 1em;
    column-rule: solid black 1pt;
  }

How would you express the same presentation in your proposal?
