I think the idea is kind of deceptive. Do people that like it, like it because of no horn, or do they like it just because it's a wider seat? I happen to like a wider seat, which you can buy pretty cheap anywhere, and I don't see that I'd gain anything by removing part of it. For that matter, if the horn part was the problem, you could saw the front half off some narrow seats, too.
