It seems like the code is already making unwarranted assumptions about the internals of ZipFile, and taking out the access to a private attribute doesn't fix that, it just makes it less obvious.

Either way, you'll want a comment explaining why this works (and which versions of the stdlib it's been verified to work with) if you're doing this from outside.
