This is not an objection, just sharing a tip that to make
Isearch history buffer-local like it's in web browsers,
where each web page tab uses own local search history,
is possible with a small code snippet:

  (make-variable-buffer-local 'search-ring)
  (make-variable-buffer-local 'regexp-search-ring)

OTOH, with using defcustom it's easier to customize this, indeed.
