Every beginner-level tutorial for scientists should state during the first five minutes that you cannot expect stability and that you should either use Python only for throw-away code or else

What is not OK is what I perceive as the dominant attitude today: sell SciPy as a great easy-to-use tool for all scientists, and then, when people get bitten by breaking changes, tell them that it’s their fault for not having a solid maintenance plan for their code.
