Do fire codes actually allow installing foam without covering it with
something highly fire resistant? Should they allow it?

Foam is made from modified materials that will not burn unless there is
another source of ignition present. Unlike a living space, there is no
heater, etc. that will start a fire. Local codes can always vary though.

Regular styrofoam is like that, and that's why I don't trust the term
"self extinguishing" very much.
