Right, the main reason for the proposal is to lock down "locals() is globals()" for module namespaces and "locals() is the namespace that was returned from __prepare__ and will be passed to the metaclass constructor" for class bodies. The change to exec merely follows because the single argument form corresponds to module execution and the two argument form to class body execution.
