no, wait, I just used google translate... They're talking about the idea above: to let the rocket be homing. However, the problem with that is that you cant' place a tank in between Jinx and your carry any more: she'll just shoot next to the tank and the projectile will home in on the carry. So if they're going to implement this feature, Riot will be forced to make the cooldown higher and nerf the damage, so it's a bad idea.
