Part of me says that you are already proposing the right answer, as these alternatives are just a little too hackish. Still, they are good enough that they should be listed in the PEP, even if only as rejected alternatives.
(1) You could add a builtin main that is false. The real main module would mask it, but no other code would need to change.
Con: Another builtin, and this one wouldn't even make sense as an independent object.
(2) You could special-case the import to use file instead of name when name == "main"
Con: may be more fragile.
(3) You could set name to (an instance of) a funky string subclass that overrides eq.
Con: may be hard to find exactly the right behavior. Examples: What should str(name) do? Maybe main should be the primary value, and split should be overridden?
