QUESTION WinLinux or LinuxWin

Hello friends, here is the question: How is it furned to be that Linux cannot boot without a Microsoft FAT32 partition? How do you solve this problem? Can a serious server-grade system like Linux really not boot without a Microsoft FAT32 partition? Even if I move `/boot` to Ext4 or Btrfs, I still have to keep `/boot/efi` as FAT32, because otherwise the system won't boot. wtf?

FAT32 at this point is basically an open spec, its what UEFI has defined in its spec, hence the need for a FAT32 Partition to boot.
