And if a native program writes to ~/.wine, what happens?
I agree. The point of wine is portability. The problem with doing something like forcing a filesystem is that one cannot forsee every possible use scenario and many things are likely to break. It also seems that wine is tending toward integration with native, not separation e.g. desktop integration, etc.
The other angle is that if one wants to use a different filesystem for their ~/.wine then they can already set this up manually.
