A function attached to a symbol could return its search direction.
Indeed, the definitions will be slightly longer, but still this is
better than defining new commands. So this could look like:
(put 'beginning-of-buffer 'isearch-match-scroll (lambda () (goto-char
(point-min))) 'forward)
(put 'end-of-buffer 'isearch-match-scroll (lambda () (goto-char (point-max))
'backward))
(put 'scroll-up-command 'isearch-match-scroll (lambda () (goto-char
(window-end)) 'forward))
(put 'scroll-down-command 'isearch-match-scroll (lambda () (goto-char
(window-start)) 'backward))

The same question applies to scroll-up-command and scroll-down-command, e.g.
in a forward search using scroll-up-command should change the direction?
Maybe this preference should be specified by the same your new option
isearch-allow-match-scroll, so when its value is t, then the enabled scrolling
doesn't change the direction. But it does this when its value is e.g.
'change-direction'.
