I would think it's that the kinds of places which value this kind of knowledge often have major disincentive to share it. I'm thinking of HFT firms as one example.
Well if any labs want to scrape my knowledge of such things into model weights or faster training runs, I do consulting at movsoft.io :-)
It really is [as simple](https://github.com/ratatui/ratatui/pull/281#issuecomment-160...) as the Molly rocket video about terminals makes it seem; I am sure the models will catch up eventually. They have to overcome a lot of bad training data in most languages, but I find in Rust they usually do ok the first time.
