Hello Baptiste,
Yes, in general, if you create a new class, Python packages can easily be generated and uploaded to PyPI by starting from the ITKModuleTemplate cookie-cutter.
This repository may be private (I cannot access the file), but since this class is already in ITK, you can contribute the wrapping configuration to its module wrapping directory. For more information on how to contribute a file, see our CONTRIBUTING.md.
After it is merged, the ITKPythonPackage ITK version is updated nightly, so you can build pre-release binaries until the next release.
Thanks for contributing to ITK!
Matt
