I guess you'd be assuming that both the original CC code and its ports are computer/AI-generated? As a lawyer, though, I'd still maintain that you wouldn't need much original human input in the CC code to kind of ruin that theory. The threshold for copyright protection isn't that high, really.

The copyright office has indicated that AI generated elements lacking human contributions to the expression (rather than input) would still not be copyrightable even if some human authored elements are made to the expression as well.

Seems like it would be a nightmare to provide evidence of what parts of a half a million line codebase were written by humans if no one bothered to track it.
