Fedora 37 'Workstation', but a better version..?

Looking at an atomic/immutable release by Fedora that is a prayer/dream come true, and possibly the way ahead for all Linux distros (eventually). That is, a secure, read-only 'host' upon which applications are 'layered' by one means or another. In this case, Silverblue uses 'Flatpaks' as the primary application source - and they are excellent - and they are backed up by a containerised version of Fedora 37 in 'toolbox' (VM?) form, as well a a third fallback of direct layering (lost on any 'host-upgrade however) of the host using 'rpm-ostree' commands in the (common across all choices!) terminal. A total eye-opener for me, and deserves a lot of attention. My 'daily driver for life', as "EB" would say: BUT I mean it...
Best wishes, stay safe...
