I agree, I don't think this is a feature that web designers should worry about. How I scroll is something that should be set on the browser level. This is sort of like a web designer writing CSS to redesign my browser tabs while I visit their site. This isn't their job. Plus, on Mac devices with trackpads, the system OS already adds a smooth scrolling to all actions we do. So when we visit these sites that add smooth scrolling with Javascript it can cause us to go insane. Because scrolling becomes insanely sensitive, with 2-3 inputs trying to control scrolling behavior (the OS, the browser, and now JS). The system is adding its own acceleration and deceleration, and then javascript is sitting on top of that trying to interpret these forces and add their own multiplier on top of those. I have visited sites that have JS implemented smooth scrolling that is so sensitive, that I can't even barely touch the trackpad without scrolling down an entire page length.
