I probably wouldn't use it either, but I guess it could be useful if for whatever reason you lost your save data after completing the game. That was what I assumed people would use an officially LockedOn Sanctioned Unlocker Feature™ for.
I should probably reveal Noman's method soon, I don't want people's minds to go to extremely disgusting places when it's really only slightly revolting. Then again maybe it's better that way. In conclusion, don't ask how Horcruxes are made.
