>If you're doing something in a way it's not in the training data set

in my industry, the "training data set" won't get much farther from public code than the barebones, generated doxygen comments we call "documentation".

But in a way you're also right. The industry's approach is fundamentally wrong, making 20 solutions to a problem with plenty of room to standardize a proper approach (plenty of room where you need proprietary techniques, but that's getting less true by the month). But an LLM isn't going to fix that cultural issue and will suffer from it.
