>A solution exists, and is nearly universally implemented: scroll wheels on a mouse, and scroll gestures on a trackpad.

So you didn't read the article huh. The very first paragraph says:

>“Ah”, they say, “that’s what the scroll wheel is for”. My friend, not everyone can use a scroll wheel or a swipe up touch screen.

Or literally the next paragraph about difficulties small/hidden scrollbars cause with other input methods, e.g. eye trackers.

What's stopping those input methods from having a special scroll gesture that is optimal for their input medium? But sure, have an accessibility override for giant scrollbars.

I thinks that of all things, eye trackers and voice controllers have the easiest time sending whatever scrolling commands, without a need to fiddle with scrollbars.
