My concerns aren't about a module reimporting itself directly, they're about the case where a utility module is invoked as __main__ but is also imported normally somewhere else in a program (e.g. pdb is invoked as a top-level debugger, but is also imported directly for some reason). Currently that works as a non-circular import and will only cause hassles if there is top-level state in the affected module that absolutely must be a singleton within a given application. Either change (disallowing it completely as you suggest, or making it a circular import, as I suggest) runs the risk of breaking code that currently appears to work correctly. Fred's point about the practice of changing __name__ in the main module corrupting generated pickles is one I hadn't thought of before though.
