As an app developer, I have to say I agree with Apple on this decision. The UDID is harmless to share, but in the days before TestFlight when I would send out Ad Hoc builds to test apps before publishing, many people would get nervous about sharing their UDID with me. I'd often be asked "is this safe? Can you hack into my phone with this?" Of course, classic Ad Hoc builds will probably still require handing over a UDID, but I would think it would be comforting for the average iOS user to see stories like this, because it gives the illusion of a little extra security and certainly helps regarding privacy. The only thing I'm worried about is how this will affect TestFlight. Without programmatic access to the UDID, the on-boarding process for a tester in TestFlight is going to become much more complicated.
