That also only works for the windows file sharing protocol. It's not even close to what KIO provided with it's protocol agnostic support. The windows UNC paths also only work on windows with windows apps. It's not a fair comparison. The real win would be the Plan 9 filesystem protocols which had the same feature but at the file system protocol level.
