You can code today with new libs, you just need to tell the model what to use. Things like context7 work, or downloading docs, llms.txt or any other thing that will pop up in the future. The idea that LLMs can only generate what they were trained on is like 3 years old. They can do pretty neat things with stuff in context today.

The context would have to be massive in order to ingest an entire new programming language and associated design patterns, best practices and such wouldn't it?

I'm not an expert here by any means but I'm not seeing how this makes much sense versus just using languages that the LLM is already trained on
