mooney, yeah there's no pressurization altitude, but above 14000 you need O2 for pilots and pax, therefore pressurization seems to be the go.
capcom, what are you getting your knickers in a knot for? Procedural separation provides no guarantee that pilots are abiding by controllers instructions, but I think a guy in the tower could observe deviations. What does a map have to do with it? Have you seen a US sectional? It's got a tonne of info on it, maybe too much.
