What about the stereotypical non-technical relative, who you've moved to Linux (because all they do is web and email and message) to reduce your family support effort. Is it reasonable to expect them to run container and run things in that? It seems at least more support load.
This "drop this in and run it" seems a lot more promising for that use case. Similar to freezing a python app, I suppose.
Just need something in the file manager to recognize container images and run them like an app.
