On second thoughts, I did not consider `all` very well in my statement. I thought only of hypothetical properties like `margin` that would cover both logical and physical longhands part of the same group. In the case of `all`, it is more difficult to figure that out, because that would potentially depend for each group (could be physical for margin, but logical for padding).
