I think we have reached the point in the thread where you concede that yes, there is somewhere where it's how it works and yes it does apply to languages that aren't C/C++.

So now you're shifting the goalposts and topic to

That was never something I was trying to debate. The topic was "why would you want ABI stability". And the answer is that if I wanted to rewrite coreutils in rust, then it'd be really useful to have synchronized crates with a stable ABI so I could potentially update those crates independent of the apps that depend on them.
