It is very rare to encounter the word "plasma", at all, in any astro article, and vanishingly rare to encounter any mention of any plasma fluid dynamics phenomenon, as such, except in solar physics. Usually we read "hot gas". There has been some progress: x-radiation is not militantly insisted to be blackbody radiation from stuff at absurdly high temperatures, anymore.

MHD is the trivial, sanitized subset of plasma fluid dynamics that rarely occurs in nature, and is hard enough to maintain even artificially. But MHD maths are easier.

I am saying that astronomers seem, from any remove, to try hard to avoid discussing things that seem to require treatment with PFD. Polar jets are embarrassing because they cannot be ignored. So, how they work is just never mentioned in the popular press.
