Actually, shouldn't we revert this change and use
(add-function :before-while ...) on isearch-filter-predicate instead?
Admittedly, currently nadvice.el does not give you access to the list of
functions so you can't directly do the equivalent of

		   (mapconcat (lambda (s)
				(and (symbolp s)
				     (get s 'isearch-message-prefix)))
			      (if (consp isearch-filter-predicates)
				  isearch-filter-predicates
				(list isearch-filter-predicates))
			      "")

but that could be remedied (even using an advice's property rather than
a symbol property on the function added as advice).
