pm.sample return InferenceData by default #4372Description
The return_inferencedata kwarg has been there for a while in pm.sample, without big bugs appearing, so we should add a DeprecationWarning in 3.11, saying that the default format will change to InferenceData in the next major release, aka 4.0.0.
