Many apps don't need to view the user folder for documents but also employ programmable scripting engines - a good example are games. It would be much more convenient to pass some sort of "sandbox me, allow network, deny home folder access" switch to Wine than to muck about with stuff like AppArmor profiles.
The usual reply to this is that Windows apps in Wine can just issue Linux system calls, so any Wine-based sandboxing is security by obscurity. You need something at the syscall layer.
Could Wine ship two binaries, one with an AppArmor profile blocking syscalls and one without? Then a simple switch could tell Wine which one to use and that functionality wouldn't need to be duplicated elsewhere.
AppArmor does not do system call level blocking.
You could use AA to confine an app to write just in $HOME/.wine/ itself.
