Thanks, no changes in other files is certainly a big plus.

This is an interesting question. I tried in other editors,
and e.g. in the editor xed that is installed by default,
this is exactly what is displayed: 1/20, 1/19, ..., 1/1.

Maybe this makes more sense, when the users will learn
what do these numbers mean.

Maybe two separate hooks could be defined? One highlights like
lazy-highlight, and another counts like lazy-count does:
(add-hook 'minibuffer-setup-hook 'isearch-read-with-highlight-setup)
(add-hook 'minibuffer-setup-hook 'isearch-read-with-count-setup)

The format of the total counter needs to be defined in a separate variable.

This can be answered only by testing with all possible cases ;-)
