It wouldn't work in MO2 like it does in the videos. These are controlled scenes in a test environment which looks to be in engine renders. In a live MP environement of a large scale, it wouldn't be like how it is in these videos, it would be very watered down in detail and not as impressive.
It would also add layers of optimization required to reduce perf impact as well as interacting with their own custom solutions for their weather systems which also tie into other systems etc I don't think SV is honestly capable.
