Their other advantage, for this application, is that gas, even highly

you are in vacuum. 20..40kV/mm ( be careful with electrode geometry.)
and that is the lightest dielectricum available.
Lightest, yes, but the power engineers have some non-obvious issues, like
recovery from arcing (they don't think trying to prevent it is 100%
reliable), that may favor SF6 (or SF6 diluted with N2) over vacuum for
operational high-power systems. I don't know the details well enough to
assess the tradeoffs for powersats, but I know there are subtleties there.
