PackagerV3 mmds do not allow the same copy behavior as v2 mmds. Previously, you could supply the module name and stream name as arguments to mmd.copy(), but that has been removed. Instead, MBS should use mmd.set_module_name() and mmd.set_stream_name()
mmd.copy()
mmd.set_module_name()
mmd.set_stream_name()
