But the original request was just about allowing completion packages
to kick in when in `isearch-edit`, and Icomplete is one kind of such packages.

Maybe something like this:
(defun isearch-completion-at-point-function ()
(list (minibuffer-prompt-end) (point-max)
(if isearch-regexp regexp-search-ring search-ring)))
(defun isearch-completion-at-point ()
(interactive)
(let* ((completion-ignore-case case-fold-search)
(completion-at-point-functions
'(isearch-completion-at-point-function)))
(completion-at-point)))
(define-key minibuffer-local-isearch-map "\M-\t" 'isearch-completion-at-point)
But I'm not sure whether this could help completion packages like swiper
to hook into isearch completion.

`isearch-complete` already activates the minibuffer conditionally
when there are completions. It could activate the minibuffer always,
then immediately exit the minibuffer when completion-at-point
finds no completions.
