You can sandbox and make it work. Somehow.
There are two problems with this:
1. You end up with 1% New World apps, and 99% Old World apps. Doesn't really change much if you mostly use an Old World app? Could get real fast reboots though.
2. There is no echosystem to shift the 1 - 99 balance. (That is what Windows and Apple had. And a firm whip.)
