yes it is un update its not a container deployment and this is in no way connected to flatpak outside of ostree

well my experiance and experiance of many other people say otherwise and most wide reaching example look at how a single miss configured package(dependancy misconfiguration) deleted Linus Sebastians pop desktop.(and no the fact that he didnt read doesnt excuse poor package dependancies that even got to that point) that could have easily been caught if composition didnt happen at runtime

On non 0 number of occasions i lost or recoverably broke arch installs while it was updating using pacman just because X or DE's WM got crashed during update because of update. just 2 examples out of many for why composition at runtime is a bad idea for linux to be a more mainstream OS
