pointer movement is application-independent, mouse wheels (and thus
scrolling) not. depending on where you scroll, nothing may happen, you
may scroll a line at a time, a word at a time, a page at a time, etc.
Putting any acceleration into scrolling obfuscates the physical
information from the device, quite likely to the detriment of the
applications that want to use it for their own acceleration methods.
