I think this was done for the sake of balance. Also, The yellow and purple variants make it look the closest to an eyeball, which could be another reason (The Ocuvigil was previously crafted with the yellow variant, which looks closer to an eyeball than the purple variant. It was changed because yellow gems are as rare as you know).

Marking an area far away will not cause it to burn in summer, since entities far from the player are paused to prevent the game from becoming too heavy and cause lag, so it can be one of itts uses. It could also be used to help newly-joined players locate a base in order to get shelter and/or co-operate with others on their own (Assuming no griefers). If you open your map at regular intervals while away from a base (Most people do), it can still function as a security camera if you check on it every time you open the map, and if you see missing structures, or see someone there with icons slowly disappearing, you know you'll want to go back early.
