Of course! Scrolling by 5 lines scrolls extremely fast when using touchpad, so 
much so that on my personal laptop in scrolls to the end of even pretty large 
files by moving my finger less than a centimeter. Also, since there is no 
tactile feedback on a touchpad, it gets very hard to predict. When swapping 
these, the ones wanting the five by five still get it by using shift.

Most software scrolls pixel wise, and that is still a ways to go for emacs, if 
I understand correctly.

The same as most other software, pixel wise. Comparable editors, like vim, 
scrolls one by one

>In what way does this help make Emacs behavior less surprising?

This should be as close to pixel wise we can get, and will be a lot more 
similar in behavior to most other software, be it editors or browser or whatnot.

Hope this clarifies the rationale a little.

Have a nice day!
