I disagree. First, I think the currently described functionality can
be used for effect. Second, even if you make it be at least as wide
as, it will not look good in the common cases -- you need to set a gap
as well. Third, the new proposal is more complex than the current
behavior (if only slightly).

Agree. Done.

Done.

Yes, this has now been added: "Omitted values are set to their initial values."
