Technically it's possible to use the SD card with open cover. The only downside is risk of battery falling out and user being able to physically remove the card. The behaviour of SD card not being available when the device is open is unexpected and creates more problems than it solves. There is a high chance, that more people accidently break their rootfs by opening the case without physically removing the card.
