The filesystem mounted on /boot/efi is a FAT formatted filesystem that contains only the EFI bits, which is basically the boot loader that used to be on the MBR. The boot loader is much larger under EFI. /boot contains the kernels and initrd files. It's larger, and it's not FAT formatted. You probably could put /boot on / for simple systems with a single disk, but no such exception has been put into Anaconda's defaults. It's just as well that it's left as is.
