We are so accustomed to seeing the bootloader at the front because of the MBR style disks before GPT. Out of tradition, most OEM manufactures still place the bootloader at the front of the disk.
Either way it hurts nothing and is functional. The problem becomes when it's in the middle of the disk and you have to delete it in order to move or resize other partitions. Since you don't have that issue you should be alright no matter what you decide to do.
