Because GTK sliders are consistent with the scrollbars in behavior.

One can wonder how much sense Page Increment/Decrement makes for
sliders, where there is no concept of a view that could be scrolled
page-wise, though.


I think having 2 or 3 distinct target areas (before and after the
handle, the handle itself) on a slider makes it a lot harder to
understand their behavior and adds a huge potential for miss-clicks with
consequences.

Using the whole slider area as single drag handle makes for a
faster/easier to hit target and avoids surprises with unintentional
stepping. Note that the value-mark should not look like a handle, then,
as it would cause users to aim at it for dragging.

Middle MB clicks and modifier-clicks are candidates for a
jump-to-this-point behavior.

All this can be found in the fader design in Ardour.

It's mainly about an additional concept, but some examples of how such
sliders could look like can be found at:
