Regardless of cache implementation, if the notebook input cells are run in a different sequence like 0,1,2,2,2,3 the output with caching there is not necessarily same as without caching and not necessarily the same as 0,1,2,2,3 ; caching alone does not achieve functional idempotency, in fact that's many more partners that can diverge when the interest is parametric reproducibility (and notebooks are already a strange abstraction for computation graphs complex enough to justify e.g. dask.cache.Cache() for, and there are reasons to not always enable dask.cache.Cache() globally (if the argument were whether auto-caching is safe enough to be the default behavior in notebooks))
