Ah, thanks for correcting me. I’ve seen Steam OS being described as immutable but never dug into it to confirm. Lesson learned.
It kind of feels like they’re just throwing out various buzzwords to catch everyone - “it’ll be like the Nintendo approach but they really want input from power users”, “it’ll work on anything and everything” etc. Maybe I’m just being a bit too cynical… ╮( ˘ 、 ˘ )╭
