I appreciate that the article wasn't written by human, but now that we have great AI tools and SVG implementation and spec, this project feels like something where a spec based property test suite would help a lot in getting AI to help to speed up the impelmentation especially as there is already a working implementation.
Of course the hard part would be in that case keeping the structure nice and clean and not a slop so that it can be confidently be submitted to WebKit, but still I believe it would worth a try.
