Hehe, will think about it, but I believe the issue is still valid, even
with good mouse support.

I do not understand what you mean. For me using the mouse wheel on x11
(as on other os) means getting a page to scroll while my mouse is over
the page, not over the scrollbar.

Auntie Nora is one of the personas we use at Canonical. We should
probably move this discussion on the usability ML, but since I do not
think you will change your mind, it's probably useless :(

True for pagers and taskbars, false for desktop background.

Additionally, when you  scroll a document you do not go for one-line
scroll, which means if your wheel event get sent to the taskbar, god
knows how many windows you skipped. You then need to do a very precise
wheel movement to go back to your window because the wheel event sent to
your pager or taskbar requires more precision than just scrolling a bit
up if you scrolled down your document too much.
Of course if you are not using a continuous mouse wheel (using a crappy
mouse, or an Apple Mighty Mouse, or your touchpad scroll area), it's
even worse.
