STR:
- Set
general.smoothScroll = falseandgeneral.smoothScroll.msdPhysics.enabled = true. - Press the up/down arrow, page up/down or home/end keys to scroll the page.
Expected:
Scrolls in discrete steps without smoothing.
Actual:
Scrolls smoothly despite smooth scrolling being disabled.
Works as expected with apz.force_disable_desktop_zooming_scrollbars = true.

What is the reason to have those prefs set that way? Seems contradictory?

Main thread scrolls already respect it, but when we moved these to be done by apz we evidently overlooked this.

Users may want to customize scroll settings to their liking and then toggle smooth scrolling on and off as they see fit from about:preferences. They could have also enabled msdPhysics a long time ago and forgotten about it, then just assumed that keyboard scrolling does not abide by the smooth scrolling setting.
