You should pay attention to when a Switch updates. There is no A/B system - the installation literally is 5 seconds after the download is finished, followed by a reboot. It makes other operating systems look downright shameful. As for backwards compatibility, Flatpak solves it, mostly. The underlying system doesn’t necessarily need to be Linux if it provides the right environment to run Flatpaks, maybe in a container.
