How would the hook be triggered? The zipimporter code would probably add
argv[0] to sys.path, and then try to 'import __main__' or something like
this. The problem is that a standalone executable python would have to
disable the standard Python command line flags and environment
variables, but they are parse *before* Py_Initialize() is called.

And I hope that the options set by the command line flags and env vars
should now come from the __main__ script itself.
