Yeah no. English is the lingua franca of computer science and programming. It's one of the few areas where language is not getting in the way of international exchange so much. It brings people together. I can check out and understand any random project on github no matter where the author is from and what language they speak. The worst that can happen is I can't read the comments. Even then most people still at least use English names for variables and functions. Nobody stops you from thinking in your native language while coding. What do you gain from IDN domain names other that nobody who doesn't speak your language can't even type or remember them? Apart from the obvious security issues mentioned in TFA. Same goes for handles or ids. Don't allow non-ascii for usernames to avoid scams. If you insist, have a separate display name that's displayed alongside.
