Ubuntu Partition Boundaries on Raspberry Pi

I recently installed Mate 15.04 from the image.

I ran fdisk and noted:-

/dev/mmcblk0p1 *      2048  133119  131072   64M  c W95 FAT32 (LBA)

On Raspbian the boot partition is

/dev/mmcblk0p1            8192      122879       57344    c  W95 FAT32 (LBA)

From what I had read in the past, the start of the partition is aligned on an 8k boundary, rather than the normal, even though this wastes a few k to ensure efficient use of the blocks on a SD card.

Is there a reason this has not been done for Ubuntu?
