The new variable replace-regexp-function is intended just to set the value of isearch-regexp-function that is used by isearch functions. And isearch-regexp-function already has 18 lines of its docstring that explains all details. This is why it's important to have a link to isearch-regexp-function in the docstring of replace-regexp-function.
