If we gave all the DataArray objects the same name when converted into Dataset objects, then I think the result could always be a single DataArray?

This would be consistent with how we do arithmetic with a DataArrays: the names get ignored, and then we assign a name to the result only if there are no conflicting names on the inputs.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,494210818

E.g., list of DataArray -> DataArray, list of Dataset -> Dataset? Effectively, we would disable the automatic merging when working with DataArray objects and only do concat (ignoring DataArray names).

I guess the confusing part is that in concat we always return the same type as the inputs, vs merge where we always return a Dataset. And of course, combine can do both!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,494210818
