I was more referring to changes in the API where the input and output suddenly have to be in different formats in the middle of a pipeline, causing a crash. What can also happen is that somehow the old format is still valid and gets processed all the same, thus yielding nonsensical results. Sometimes a lab devises their own format which no one else uses, and the specification may be updated without notice between the moment they publish and the moment you try things out. Most people have no idea about things like 'backwards compatibility', 'unit tests', 'containers', etc. Code is just a tool to them and the fact that they had to write some is annoying them in itself.
