import Sofa does not cleanup

[alxbilger]

Consider the following Python code:

import Sofa
import json

if __name__ == "__main__":
    object_factory = json.loads(Sofa.Core.ObjectFactory.dump_json())

It warns at the end of the program:

[WARNING] [Sofa.Simulation.Graph] the library has not been cleaned up (sofa::simulation::graph::cleanup() has never been called, see sofa/helper/init.h)
[WARNING] [SofaSimulationCommon] the library has not been cleaned up (sofa::simulation::common::cleanup() has never been called, see sofa/helper/init.h)
[WARNING] [SofaSimulationCore] the library has not been cleaned up (sofa::simulation::core::cleanup() has never been called, see sofa/helper/init.h)
[WARNING] [SofaCore] the library has not been cleaned up (sofa::core::cleanup() has never been called, see sofa/helper/init.h)
[WARNING] [SofaDefaultType] the library has not been cleaned up (sofa::defaulttype::cleanup() has never been called, see sofa/helper/init.h)
[WARNING] [SofaHelper] the library has not been cleaned up (sofa::helper::cleanup() has never been called, see sofa/helper/init.h)

I can remove this warning with import SofaRuntime. This is because there is a static object of the class SofaInitializer that initialize and clean. But it is only in SofaRuntime. Should it be moved into the Sofa module (if possible)?

I would naively say "yes"
