Perhaps - and most folks do (in principle) just want to put files on a computer and start a process. But context changes and needs have become more sophisticated, particularly needs in isolation, consistency, elasticity. I think that the capabilities of traditional Unix kernel mechanisms, packaging systems, and userland tools, have lagged behind demand. There's still opportunity for these needs to be met with refinements to standard 'nix mechanisms. I'd contribute to such a project, if it became the explicit design direction of a major distro.
