That is a valid point.

    Well, I'm not sure, I'd expect mouse-1 to have the exact same effect as
    mouse-2 no matter where I'm clicking...

That is a valid point too.

So maybe the mouse face should cover the whole line.
Or perhaps -- though this could take more work -- the line number
should also highlight, but separately.  Either one would achieve both
of the goals above.

    So I think the question is not whether to make mouse-1 to have the
    exact same effect as mouse-2, but why mouse-2 sensitive areas are
    bigger than areas with mouse-face=highlight in the *Occur* buffer.
    I recall that the reason for that was to reduce flicker (especially
    on large context areas in the *Occur* buffer).

I think part of the reason may have been to help show the boundary
between the line number and the line contents.  That is why I suggest
that each of these parts of the line could highlight separately.
