On the contrary, this is going to make URLs hard to use and would drive it to irrelevance in some countries if IDN usage becomes more common. Take CJK languages for instance. There are just so many characters that you are required to use predictive typing for every piece of text. This means that it's impossible to type CJK URLs with deterministic keypresses as you're constantly choosing suggestions which gets reordered all the time. As for the homograph problem mentioned in the article, that's not an anglo-centric fluff. It's an actual major problem that affects speakers of all languages. It hinders the ability of people to reliably type or recognize domain names. That's going to cost some people their life savings. Overall, IDNs would cause more harm than good by making URLs unreliable. It would just serve to empower search engines.
