I feel that I am 50:50 on it, immutable at least conveyed more information about what it is while Atomic feels a lot more “buzz-word-y” and does not convey as well what it means. Regardless, I’d say the bigger issue is keeping the old Silverblue & Kinoite names, they really should change them even if it means having a ~2 year period of having “Formerly Silverblue / Kinoite”.
