I think a fully isolated developer mode user would be great - similar to Google ChromeOS would be interesting. While there are some drawbacks in that you wouldn't be able share files/clipboard as easily, there are more ways to ensure more complete isolation. I could forsee containerization being much more prone to social engineering of a novice non-technical user (i.e. stealing the clipboard, accidentally giving file access, etc.)
