This code has to change now for the tests to pass. We have to not try and set

        .numeric_leading_zeros(allow_leading_zeros)
        .nonnumeric_numbers(allow_nonnumeric_numbers)
        .unquoted_control_chars(allow_unquoted_control)

at all if strict_validation is disabled. And this goes for all of the APIs in this file because of the assertion that was just added in.
