Right. But note that "cmd.exe" doesn't just mean running cmd.exe
interactively in a console window, but also C's system() and popen(),
Python's subprocess.Popen(), Windows' ShellExecute(), etc.

If the .py extension is removed, bash will still recognise it as a
script via the shebang, but native Windows APIs won't be able to
execute it.
