I haven't re-read the bug report, but my impression was that someone has
written a patch, but it hasn't been accepted, and there was dispute
about it, so there's no guarantee it's going to get in.

The patch allows for faster scrolling by sending multiple events for
each wheel click. How do you send less than 1 (but more than 0) clicks?

Desirable, perhaps. Feasible, I don't think so. It seems to me the real
problem is that the wheel just isn't as fine-grained as the movement of
the mouse - my mouse appears to have 24 clicks/rotation, and it has no
way to measure smaller movements than that. So the only adjustment
possible is how far per click, and that needs to be measured differently
depending on whether the app is (viewed as being) explicitly line based,
the way the OP wants to see their spreadsheet, or effectively
continuous. And that's up to both the app and the user, and changing
what happens in the driver can only reduce the options for those. IMHO.
