Just to avoid misunderstanding, I do not mean to say that the
init-apply-state helper that should have been introduced in 07/xx
would gain a new caller-supplied parameter ws_error_action.  This
step would have a patch to the function that does something like:

 static void init_apply_state(struct apply_state *s,
                                 const char *prefix)
 {
         memset(s, '\0', sizeof(*s));
         s->prefix = prefix;
         s->prefix_length = s->prefix ? strlen(s->prefix) : 0;
         ...
+        s->ws_error_action = warn_on_ws_error;
 }

without having the caller supply what error_action should the state
be initialized with.
