It's likely the camouflage system was simply there to prevent any evil entity passing by from noticing an anomaly (they'd just be flying over an island). Aside from malevolent or insane Great Beings, there were also other evil entities on Spherus Magna (the Element Lords, for example), along with potentially other forces in other worlds that would have coveted the Mata Nui robot's power and technology. The Great Beings created a trap-filled maze just to protect the power source of a much weaker prototype robot, for example.

I really hope it's true that they're reannouncing Bionicle. Not just because the lore halted midway (I want to see Velika try to take over Spherus Magna), but also because there's still so much potential for amazing sets out there, even if Lego just decided to sell MOCs. The Karda Nui vehicles were extremely well-designed, and I still think the Bohrok are among the best sets ever designed.
