By your argument it should have been able to just remember Pandoc existing implementation then? But it didn’t, you think they can only “remember” small code based well enough? I doubt that. Especially since after using LLMs quite a bit I am confident I could write my own specifications for something and LLMs would be able to do it properly, despite definitively not having seen it before.
