Whether or not something needs a scrollbar to show up when there's 
overflow is something you need to decide on an element per element 
basis.

What that scrollbar should look like is something that you may 
sometimes want to decide on an element per element basis, but you may 
also want to make page-wide (or widget-wide, or component-wide... .i.e
 non local) decisions, and that's a lot easier to do if they cascade 
separately. And it gives better fallback behavior when some values are
 not supported: `auto` is a better fallback from `stable` than 
`visible`, which is what you'd get if you're not careful.

Based on that, I think that it makes sense for the values we are 
discussing now to be in a different property than the choice between 
`visible` vs `auto`. By that logic, it could make sense for the choice
 of `scroll` vs `auto` to be in that same other property as well, but 
too late for that.
