You can travel to the point where the new system should be, but you won't see anything without a hyperjump, yes the distance has been done, there's just nothing there. Many people have tried, I mean there are 400b star systems, you can't store them all in memory at once so there has to be a loading screen somewhere, and from one system to the next is probably a convenient spot to do it, the procedural key is run and system generated during the jump so only one system is loaded into memory at a time.
So the point of difference is this, you can't travel between systems because the system isn't generated, you can only travel to the point where the system should be, this is easily done by anyone with time and patience, but it is by no means traveling between systems in that meaning of the word, even the star isn't there.
