As a software engineer, I think this belief is incredibly naive. This is like saying "surgeons should be fungible. They all have a grasp of anatomy and are good with scalpels". As a patient, do you really want a knee specialist doing neurosurgery? As a customer, do you want a frontend web developer writing code for 8bit microcontrollers? They both write code into a text editor, what's the difference? I've worked at companies that (implicitly) held your belief and the turnover was always incredibly high because nobody sane wanted to work in a place that treated them like a cog.
