I’m not sure I get your point. Lots of physics terms are description-by-analogy and technical terms at the same time, like color in QCD or inflation in cosmology. Scientific papers mostly use wormhole.“wormhole” is a description-by-analogy. It was certainly first used by physicists, but it’s not a scientific term. It’s quite common for things to have common name and a technical name, eg “rotary wing aircraft” is more commonly called a helicopter.
