Because we are not sure what and where can be broken when we change something, most often we are fixing bugs using just minor tweaks, adding guards here and there, adding more kwargs. That strategy may suffice for a first-aid. But in long terms it accumulates more and more complexity and over twenty years we have what we have. I think it might be wise (at least once in a while) to invest some time in serious refactorings aimed at reducing accumulated complexity. Keeping backward compatibility wherever is possible is great. But I wish that we stay open also for the cases when breaking backward compatibility in certain areas can bring great reduce of complexity. In such situations, perhaps we may ask users to vote or to present their reasons against breaking backward compatibility. I don't think it is wise to keep backward compatibility forever. If there is a chance to improve code quality or/and its readability by breaking backward compatibility I would suggest keeping it for some limited time, and announcing that it will be dropped in one of the next releases. That way users will see deprecation warnings and they would have time to adjust their code accordingly. They would be able to ask for help on migration to the new API. If after such announcement and in provided period of time some users still keep the old deprecated code in their scripts, I think we shouldn't feel guilty for breaking their scripts at all. That way, project keeps a chance to advance. Otherwise it is bound to the limits of its first version or the limits of some ill turn in its evolution path.
