> A scrollbar is not only a control, it's also an indicator.

Thank you! finally someone understands what a scrollbar is for. It primary job is to show the user that the document is bigger than the window, and secondly, to show which part of the document is visible. Letting the user scroll around is not the primary function!

I was genuinely surprised when Apple started hiding scrollbars by default in macOS. Their UI designers clearly don't have a clue what the basic UI controls really do.

Not just that "the document is bigger than the window" but the best scrollbars tell you, approximately, how tall the document is in relation to the window height! Proper scrollbars are, possibly, one of the best UI elements ever invented.
