If they stick it after the real one, it has no effect. If the user 
sticks it in front, it's an installation issue, and the user's 
responsibility. If an author sticks it in front, it's a dirty trick that 
may or may not work.

Of course. The problem here is that it's all implicit and there's 
no way around it.

 sys.modules['os'] = mydirtyhack
is pretty obvious. Putting an os.py (or os/__init__.py) inside a 
package is not. And once it's done, there's no workaround.
