Why is the watchdog timer not disabled in the LED example?

    // let mut wdt0 = timer_group0.wdt;
    // let timer_group1 = TimerGroup::new(
    //     peripherals.TIMG1,

    // let mut wdt1 = timer_group1.wdt;
    // rtc.swd.disable();
    // rtc.rwdt.disable();
    // wdt0.disable();
    // wdt1.disable();
    println!("Hello world!");
    // Set GPIO5 as an output, and set its state high initially.
    let io = IO::new(peripherals.GPIO, peripherals.IO_MUX);
    let mut led = io.pins.gpio5.into_push_pull_output();

    led.set_high().unwrap();

  
    let mut delay = Delay::new(&clocks);

    loop {
        led.toggle().unwrap();
        delay.delay_ms(500u32);
    }
}

When should I disable the watchdog timer?

Since https://github.com/esp-rs/esp-hal/releases/tag/v0.12.0 the WDT get disabled by the HAL so there is no need to do it manually anymore
