I'm the person working on that fork. Yes, it has now diverged 200k+ lines, but half of that is specs, research and documentation and includes a month worth of work.
The comment in question was a small feature of about 1.5k lines changed and it was solidly tested.
Eh, fair enough. 1.5k is reasonable. Have you tried just writing it yourself instead? It's likely it'll be less than 1k lines and you should have no problems writing an implementation yourself if you understand the structure of the LLM version.
