Actually, looking to the future, there's nothing that prevents remote-helpers with 'export' to support dry-run, except this patch, so:

--- a/transport-helper.c
+++ b/transport-helper.c
@@ -789,6 +789,11 @@ static int push_refs_with_export(struct transport
*transport,
        struct string_list revlist_args = STRING_LIST_INIT_NODUP;
        struct strbuf buf = STRBUF_INIT;

+       if (flags & TRANSPORT_PUSH_DRY_RUN) {
+               if (set_helper_option(transport, "dry-run", "true") != 0)
+                       die("helper %s does not support dry-run", data->name);
+       }
+
        helper = get_helper(transport);

        write_constant(helper->in, "export\n");
