But that requires either
1) the app to be aware of \\?\unix, or
2) Wine to map \\?\unix/foo/bar when no drive mapping to /foo/bar exists.

#2 would also require some way to be configured to allow the
equivalent of removing the default Z: drive mapping for people who
want it. However, it would not provide any additional functionality
and could easily be considered a waste of time. Of course, that's not
up to me ;)

AFAIK, the main reason people remove the Z: mapping is a security
concern. It's not an issue for me, but some people like to restrict
the files that win32 apps can access to a subdirectory in $HOME. If
there's some workaround to access files outside the drive mapping
(assuming pure win32 of course :D ), then unless it can be disabled by
the user, it's a security breach.
