Interesting point. Though I missed the mentioned discussion, I'm not sure if a new property would really make things easier: Is it harder to understand the "collapsing margins" rules [1] or (presumably) three new properties (including a shorthand property) with three new values, like for example

  margin-collapse: standard|none|inherit
  margin-collapse-top: standard|none|inherit
  margin-collapse-bottom: standard|none|inherit

Would that be helpful? What does it mean for implementations, too?

You can achieve "table-like" visualization (including same height) with the "display" property, for example

  <div />
  <div />

  div { display: table-cell; }

Also, the cascade [2] "already" defines what declarations are applied (unless I misunderstand "may even override the designer-set values").

Great.
