The other factor that arises from this is that CMEs, of all the various dangerous stellar eminations, appear to be most responsible for planetary atmospheric erosion so anything that mitigates their effect has got to be good in terms of planetary habitability and most of all in M dwarf systems where the «habitable zone» is close to the star and well within the region of synchronous rotation.
