The overhead from optimizing contraction paths is probably very small relative to the overhead of Xarray in general, so I would support setting `optimize=True` by default in Xarray, and/or using opt-einsum automatically if it is installed. JAX always use opt-einsum  (opt-einsum is actually a hard dependency) and I have never heard any complaints.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1672288892
