The sovereign remedy for a curtain-burner is a unique plug to an external box that contains the resistor and heat-sink assembly. A nice, fat DALE aluminum resistor of the appropriate rating does well.

In this way, the radio does not get plugged into the wall by accident (nor anything else), and the external box can have a fuse, switch and other niceties as well as serve multiple radios.

Safety is a good thing, and despite the fact that our parents survived all sorts of deadly things such as a lack of seat belts, hard dashboards, Open-mesh electric fans with metal blades, and much more, there is no reason to lean into a punch.
