I agree that isearch-mode-end-hook should be customizable.
Then initially we could provide at least one choice -
a hook to move to isearch-other-end on exit:

isearch-wrap-function could be customizable in the same way with 3 options:
pause before wrapping (default), no pause, no warp at all.

And these as well.

There is no WIP until you create a feature request.
