Software Mod freeing 60MB reserved NAND partition on Netgear R6220 Questions

So, the R6220 has 128MB NAND, but 60MB is a reserved partition.
Using the kmod-mtd-rw package, one can potentially recover a portion of the reserved 60MB.
I am wondering, now that I have actually gotten a substantial amount of storage recovered, can I use this for more storage for additional packages.
Or more generally, what is a practical use for the recovered MBs on the NAND?
