A key definition is as simple as defcustom.  Instead of:

(setq isearch-bind-C-h-to-isearch-mode-help t)

you can put in .emacs:

(define-key map "\C-h" 'isearch-mode-help)

The main question is what should be the default.  For novices, who
don't know how to configure Emacs, the default binding of C-h to
`isearch-mode-help' is very helpful.  More experienced users can
put in .emacs:

(define-key isearch-mode-map "\C-h" nil)

if C-h is bound to `isearch-mode-help' in isearch.el by default.
