Quoted from ryanwanger:I removed mine. Once or twice I’ve since seen a Denogorgon mode started by a ball going in the back way (which is what I presume this wire was designed to prevent) but it’s so rare that I wouldn’t worry about it.
Even with the gate in there I have had it sneak in with a ricochet shot from the right flipper. When my gate fell out I stretched it and then put it back. Fell out the first time around 50 games and so far, after stretching and over 500 games, it has not fallen out again. I would not put it back without stretching it out some and it doesn't take a much stretch to resolve it. Had they just made the wire just 1 mm longer this would not be an issue. From what we have seen the replacements are not any different so getting a new one from stern will not resolve it.
