Not to mention that the actual controls in a car (from gearshift to button to change the brightness on the on-board display to 'open garage door' button of a built in radio wave thing) are never called chrome for fairly obvious reasons.

However, jargon words are just jargon words. There really are only two options:

1. Police them ruthlessly. Even if the word would only cause confusion in the amateur / casual observer, they must be eliminated anyway. I venture that this means almost all jargon words must be turned into words totally devoid of meaning. Jargon is useful - nobody wants to spend the same 3 paragraphs to convey a complex but very common concept - they invent a word for it. So, are we ready for the 'floobargle' and the 'glorpnitz'?

2. Just let them be, and instead police the idea that words that are jargon imply anything at all. Police the idea that their plain english dictionary definition holds any relevance beyond being a memento for what the jargon word is truly meant to convey.

In other words: The problem lies with those who realise 'chrome' is a jargon term and then kneejerk into '... it is frippery' anyway. That's stupid. Those who do that should be ridiculed.

I think that's the only way partly because that feels right and because I think it would lead to eliminated of jargon (bad endresult) or always ending up with jargon that is just a random word that has no meaning at all and wasn't in any dictionary.

No, it's the only feasible way, because of pragmatic reasons: Changing existing jargon? Hoo boy. That is extremely difficult.
