Oh, I didn't read it either: there is the link to the message I was looking for.

I can't tell the future, but there's no reason to avoid them at the
moment. Perhaps you are over-using them a bit though. For example,

    (when-let (count (and arg (prefix-numeric-value arg)))
      (isearch-repeat-forward count))

can be simply

    (when arg
      (isearch-repeat-forward (prefix-numeric-value arg)))
