Physics and Large World Coordinates

I was doing large world tests and noticed that while collisions work with large coordinates the physics will still kill your object after 20k. I am assuming this is because the physics is still floating point at this point. I tried a character that was on a platform that was 4k above a planet and it worked fine. Space ship did not. Is there any plan to convert physics before 5.0 as well as the rendering? Otherwise it looks like I will have to break out my physics for game developers book.
