It seems like a nerf to Tractor, but it really isn't in my opinion. The sole benefit for the defender is never being forced out of the playing area anymore, when a tractor move puts you facing an edge too closely. That's it. Otherwise, it's still the same basically. Let's face it, most of the times the tractoring player decides to move the opponent is when it would put the ship on an obstacle. Now that Gas Clouds have been changed at the same time as this new Tractor rule/effect, well no obstacles are "safe" anymore and are all worse really when combined with the new tractor rule. On an asteroid, the defender won't be attacking anyway so deciding to gain a stress on top of the (very) possible damage from the roll? I don't know. Of course you can assure that you won't go over the asteroid again with you maneuver template on the next move, but still... On a debris cloud, you already gained a stress, so gaining a second? On a gas cloud, well you have 5/8 of a "chance" to gain a strain token, so your agility is most probably reduced and of course you lose yet another green die from the tractor. So gaining a stress on top of that?
I would have also much preferred the rule mentioned earlier in here: the tractoring player must decide between moving the tractored ship, then removing the tractor token(s) afterwards (no reduced agility), or not moving the ship and keeping the tokens for the reduced agility. That's a real decision, and a much simpler solution.
