Agreed on the accidental reimplementation of something trivial. The distinction of what is trivial will be harder to clarify in the future, however the language models in the future can also help identify the provenance of substantial parts of the code and eventually it will be easier for GNU, if they care, to have a strong argument. I suspect GNU will not care until somebody plays foul, so GNU can wait for a long time until that happens and until the tools are substantially better. I just find it a little sad that the effort is bifurcated into competing camps. Maybe eventually gnu binutils will also start a rust clone for parts of their binutils and make this effort obsolete at the technical level.
