Yet it is rare someone ever needs to write a PNG decoder.

In the unlikely event you did, you would be doing something quite special to not be using an off-the-shelf library. Would an LLM be able to do whatever that special thing would be?

It's true that quality doesn't matter for code that doesn't matter. If you're writing code that isn't important, then quality can slip, and it's true an LLM is good candidate for generating that code.
