It makes a lot of sense for me as a Win-Mac-Linux user too. Only 2 apps are keeping me on Windows (Rhino + TouchDesigner), I don’t use my M1 Air for 3D work, and I would happily switch to Linux if I didn’t have to switch back and forth with Windows.
I don’t know what this switch would mean in terms of McNeel development time and resourcing, but a WIP using the off-the-shelf tools mentioned above is intriguing.
