Can non-American PhD students stay in the United States during the academic year 2020-2021 if all their classes are online?

I’m reading on https://thehill.com/homenews/administration/506072-ice-tells-students-on-visas-they-must-leave-us-if-schools-go-online (mirror) that the US government has the bright idea to refuse students of purely online courses (e.g., Harvard University) to stay in the US for the 2020-2021 academic year. Does that impact PhD students in computer science? I’m asking for this specific population as
one could argue that PhD students need to meet their advisors face to face on a regular basis, though computer science typically doesn’t require a student to physically access a lab and meetings with advisors can be done online (sometimes less conveniently for people uncomfortable with using online shared whiteboards).
