It sounds to me the question is ""how do we cast dtypes when multiple array libraries are participating in the same computation?"" and I am not sure I am knowledgable enough to make any comment.
From the array API point of view, long long ago [we decided](https://github.com/data-apis/array-api/issues/399) that this is UB (undefined behavior), meaning it's completely up to each library to decide what to do. You can raise or come up with a special rule that you can make sense of.
It sounds like Xarray has some machinery to deal with this situation, but you'd rather prefer to not keep special-casing for a certain array library? Am I understanding it right?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1655290694
