Maybe also a way to easily register new search tools? Otherwise one might be locked into the available options again - and if there is a new tool the interface might be not that stable, so there is the danger that it breaks until there is a new emacs release.

Indeed, the same way as it's already used in

(defcustom grep-find-use-xargs nil
  "How to invoke find and grep.
If `exec', use `find -exec {} ;'.
If `exec-plus' use `find -exec {} +'.
If `gnu', use `find -print0' and `xargs -0'.
If `gnu-sort', use `find -print0', `sort -z' and `xargs -0'.
Any other value means to use `find -print' and `xargs'.

This variable's value takes effect when `grep-compute-defaults' is called."
  :type '(choice (const :tag "find -exec {} ;" exec)
                 (const :tag "find -exec {} +" exec-plus)
                 (const :tag "find -print0 | xargs -0" gnu)
                 (const :tag "find -print0 | sort -z | xargs -0'" gnu-sort)
                 string
                 (const :tag "Not Set" nil))
  :set #'grep-apply-setting
