People who grew up with assembly language or locking primitives are fairly likely to use compare-and-swap because it's literally the commonly understood term for it.

TIL, thanks for the context. What I was getting at still stands, LLM's seem to love a lot of words-with-hyphens which might be grammatically correct, but I've never seen a human actually type.

Compare-and-swap is a hardware instruction, and beyond that a desirable pattern for dealing with concurrent writes.

For compare-and-swap I have even got a lock less queue that I implemented with it.
