[csswg-drafts] [css-gaps-1] Should `rule-break` and `rule-outset` accept two values? (#13097)

cdoublev has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-gaps-1] Should `rule-break` and `rule-outset` accept two values? ==
[`rule-break`](https://drafts.csswg.org/css-gaps-1/#propdef-rule-break) and [`rule-outset`](https://drafts.csswg.org/css-gaps-1/#propdef-rule-outset) are currently defined as setting the corresponding `column-rule-*` and `row-rule-*` longhands to the same value.

While accepting values for both longhands does not seem significantly useful (one vs. two declarations):

  - the shorthand must serialize to empty string when the longhands are not declared to the same value
  - [`gap`](https://drafts.csswg.org/css-align-3/#propdef-gap) accept values for both `column-gap` and `row-gap`

So why not accepting two values?
