Correct me if I'm wrong but this means the referer will show up as t.co, meaning that you can just as easily track twitter referals, just by looking for t.co rather than twitter.com?
The downside is that you can't see which twitter URL it came from, but in my experience that was rarely useful as so often it came from users' home pages. And the upside is that it will show a t.co referal for non-web twitter clients, e.g. mobile apps.
