For me, there is no difference with Emacs 28. To see this best, make the
following customizations:
(setq mouse-wheel-progressive-speed nil)
(setq mouse-wheel-scroll-amount '(1 ((shift) . 1)))
(and make sure that in the Mouse Options part of the Accessibilty panel of the
general System Preferences of MacOS, scrolling with inertia is enabled.)
