@simevidas if I am creating a space for it then sometimes I would like the option to have something in that space - if only to help explain to the use why there is extra space - for example, I had scrollable region with a sticky header - but with scrollbar-gutter:stable the header ends short of the edge because of the space reserved for a scrollbar and it looks iffy. So I would like more options to handle it in different ways as necessary.
