Imho scroolbars are unneeded on computers with properly made keyboards. People are desperate to use scrollbars only when the PgUp, PgDown, Home and End keys are not quick to reach.
This is the real battle to fight for. Vote with your money and stop buying computers with stupid keyboards.
Scroll bars are a visual indication of how much content there is off screen/window and where I am in it. There are more uses to it than just dragging or clicking it with the mouse.
I can count the amount of non technical people I have met who use the navigation keys, on a single hand, and every single one of them has a finance related job.
Even most devs, particularly younger devs, never use navigation keys.
