The notable thing that these LLM-generated ports aren't doing is _rewriting in Go_. TypeScript 7 is a lot faster than the JS/TS-based version 6, but memory use is a major bottleneck.

However, it mostly represents a mechanical port of the old codebase to Go. What I haven't seen anyone do is try a true rewrite in Go optimized for performance (whilst keeping a strong emphasis on readability).
