Sure, but the point is that some OS vendors will refuse to make scrollbars that fade away after scrolling is complete, because this is in their view a user choice not an author one. Also some OSes do not have that kind of scroll bar.
In that case:
* We can say that they're allowed to display a "normal" (non overlay) scrollbar on top of the content, as suggested in https://github.com/w3c/csswg-drafts/issues/4501#issuecomment-558184710. But this would be bad for users, as the content would be partially obscured.
* We can say that support for this value is optional, and when not supported, it must be rejected at parse time, so that `@supports` can be used. This is probably doable, but would probably require for some UAs that *can* have overlay scrollbars, but chose not to in certain modes, to be able to toggle support on and off from the parser at run time, based on that user setting. Not sure if people are willing to do that.
