Even if there were a performance cost (compared to the actual behaviour), it could be easily avoided by using all dims as input_core_dims couldn't it? IIUC, all dims should be broadcasted unless they are in input core dims, so it broadcasting could still be avoided without problem.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,457716471
