Looks fine, yes.

Ah, no I was thinking rather of something like

        (lambda ()
          (setq-local completion-ignore-case case-fold-search)
          (add-hook 'completion-at-point-functions
                    #'isearch-completion-at-point-function nil t))

This way, things like `company-mode` can use it (tho IIUC company-mode
currently doesn't work in the minibuffer) and `isearch-complete-edit`
can be an obsolete alias of `completion-at-point`.

Yes.  What I meant is that `isearch-complete` can't be turned into
a mere obsolete alias of `completion-at-point`.

FWIW, I think it might be worthwhile trying to rewrite isearch such that
it always uses the minibuffer (instead of using a transient keymap and
displaying the search string in the echo area).

Then `isearch-edit` would simply change the minibuffer's keymap such
that we only exit the minibuffer in the "usual" way.

In such a setting `isearch-complete` could be a simple alias of
