Yes, you're exactly right: I haven't used a mouse wheel or the PgUp/PgDn keys to scroll in years, which explains why I haven't noticed any difference from changing the setting (as another commenter also pointed out). What I didn't realize until now is that 'smooth scrolling' in VSCode etc is an added animation to turn what was originally a discrete, instantaneous change into an gradual animated transition. Smooth scroll in this sense is (I suppose) more about enhancing visual appeal or aiding accessibility for users who have difficulty tracking abrupt changes on screen than about allowing more precise control over scroll positions.
