I forgot to connect the dots.

When search-invisible is t, perform-replace can replace matches
in any invisible text, but does not display it when prompting the
user for confirmation.

When search-invisible is 'open, perform-replace can replace matches
only in hidden text (invisible through an overlay), and displays it
when prompting the user.

We lack a way to reveal truly invisible text when performing a search
and replace.  The URL of a bracket link in Org is an example of such
truly invisible text.

Juri's solution to add 'open-all could also be used in perform-replace
to let the user see truly invisible matches before replacing them.

So the *solutions* are related, if not the problems themselves.
