Supply chain attacks are so scary that I think most companies are going to use agents to hard fork their own versions of a lot of these core libraries instead. It wasn’t practical before. It’s definitely much more doable today.
I was thinking about this as a bull case for human developers. Seems if you're worried enough to do this you're not going to have LLMs write the new code.
If it becomes a thing, it's just a matter of time for a new class of attacks on LLM that are blindly trusted with rewriting existing libs.
Even better would be to not use so many libs. Most use cases will do fine with native `fetch`.
