>From a security standpoint "removable" vs. "non-removable" is what really matters. You don't really want someone to plug a usb key or SD card into your device and accidentally boot from it. Also, changing the default boot order for an already supported device is probably going to cause problems. Something to keep in mind when devices get converted to the new mechanism.
