Probably not. It might just make applications that never bothered to use the Unicode Windows APIs to support Unicode. And there's still a lot of them. In the past you could use CP65001 in some places to get sort-of UTF-8 support, e.g. in batch files. However, there have been quite a few problems and bus with that approach. Maybe they've just fixed those and added an option to use CP65001 ad the legacy codepage.
