Default [Q] Deleted partition called "growth"

Hi,

after flashing, restoring and wiping quite alot, i ended up with a official 4.4.2 open ROM, rooted and with custom recovery but only 16GB space on my 32GB model.

So i used parted via adb from cwm to increase the userdata partition. The problem was, that there was a partition called "growth" between the free space and the userdata partition. Because it was not in a fileformat that parted was able to recognize, my only option was to delete it.

Does anyone know what this partition is used for? Is it a problem that i dont have it anymore? The phone seems to be working just fine.
