Redundancy is almost always a good thing. If something goes wrong with one form, they have the backup while they fix it.

There is a road going up there, and as another user pointed out there are overland cables connecting it to the rest of the system.

Sort of. With something as simple as a hammer sure, but when the hammer is equipped with a 9mm pistol then it falls under different safety standards that deem the tool inherently unsafe. A physical tool would be recalled if somebody got hurt in an unintended way.
