For debugging purposes, you may need to look at a signal on an oscilloscope. Therefore, you will want to make sure you can get access to the signals, particularly with BGA devices where it might otherwise be impossible. This can be done by bringing a via all the way through the board or other times where a pullup/pulldown is needed you can probe at the resistor. Having a GPIO brought to a test point or an LED can be useful as well.
Additionally, CLKOUT and XF pins are useful signals for debugging the PLL and bootloader.
