+1 to that. Add on top of it that by design, a lot of Python coders are not professional programmers, and you get yourself a better model of why migrating was so long. People coded an untested unstructured project that worked on their machine. It was enough to get the job done, and was a big reason they choose this language in the first place. But migrating that is not fun. Plus they didn't understand their own system, so touching it on such large scale seemed overwhelming, and hence the "it's too hard".
