I think this value is used in contexts that are different enough to
behave differently in this respect.
Examples:
1) I want help-button-action to bring me to the function's definition,
and I generally want in the middle of the screen. Same for imenu, etc.
2) I really don't want to see empty space after the contents in the
compilation window. But as much as half of the window may be empty right
after compilation because of the point recentering.
3) Ideally, if I move around with next/previous-line, I don't want
sudden jumps and recenterings. Same thing with beginning/end-of-defun
(so setting scroll-conservatively to a value larger than 0 is not a real
solution).
I'm sorry, but the problem you describing is entirely unclear to me.
You didn't say what value, if any, did you set scroll-conservatively
to, nor if you have any other scroll-* variables customized to
non-default values. If you don't customize anything, Emacs always
re-centers when point goes out of sight. When point is re-centered, I
don't think you can ever have half-window of empty space, because of
the way re-centering works.
Given this lack of information, I don't understand how you get the
adverse effects in your 3 examples. Please elaborate, perhaps
separately about each of the examples.
