Necessary for the first partition to be the FAT partition!?

Hi everybody, in the official documentation, it's written: It is no longer necessary for the first partition to be the FAT partition, as the MSD boot will continue to search for a FAT partition beyond the first one. https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/bootflow.md...
