Relative to camera rendering

I read that 2018.1.1 will render objects making them relative to the camera position.
That means that if camera is in 10000,0,500 and object at 10000,0,600 object will be rendered relative to the camera, so GPU will use verts at 0,0,100 position

If that is true (i may be wrong), how long to switch floats to doubles in transform, so i can have a camera in the space and record a random car surfing the space and moving around the sun?

Because with that new feature in 2018.1.1 relative positions of rendered objects will fit into the float precision, so GPU can stay working as now. Like i see most of the work will be done, just missing to replace Vector3 to Vector3d in some classes.

 

I'd like that too, I mentioned it as well on my post here:
https://forum.unity.com/threads/double-support-for-burst-compiler-and-new-math-library.520394/

I'd suspect biggest limitation to make that happen is that Unity doesn't in general want to implement systems that work only partially, and only having Transforms in doubles wouldn't help much if their physics engine is limited to single precision floats (physx can't do doubles).
