Not true, unfortunately. Which sucks... JTL would be so nice.
People have said SWG and JTL used seperate engines, I dunno how true that is.
However the newest versions of the Hero Engine do support "space"....... and frankly upgrading the whole game to that might solve a lot of other problems too.
If all they do is mildly take space off the rails then it's never going to be what most people want.
