I've definitely run into websites where you can tell the developers only ever tested their work with a smooth scrolling multitouch trackpad.

Clicky vertical only mousewheel scroll? Sorry, spent $6000 on the maxed out laptop but can't get a $10 mouse to go with it.

Enjoy scrolling two pixels per wheel revolution because our scroll hijack only works right on trackpads.

On this specific issue: scrolljacking is always bad because the web simply doesn’t expose the necessary primitives to make it not bad for at least some people. Search my comment history for a little more detail and discussion.
