Well ... that part isn't nonsense, though I agree it shouldn't be a dealbreaker. And it means we should work towards making such support demands minimal or non-existent via easy containerization.

I note with frustration that even the Docker people, whose entire job is containerization, can get this part wrong. I remember when we containerized our startup's app c. 2015, to the point that you should be able to run it locally just by installing docker and running `docker-compose up`, and it still stopped working within a few weeks (which we found when onboarding new employees), which required a knowledgeable person to debug and re-write.

(They changed the spec for docker-compose so that the new version you'd get when downloading Docker would interpret the yaml to mean something else.)
