If we do want this use-case to work out of the box, then I too agree that a new top-level method would be best. `stack` would've been a good name but that;s taken.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1588461863

I propose `join=""exact"", data_vars=""minimal"", coords=""minimal"", compat=""override""` 
1. this would only concatenate variables that have `concat_dim` (if none do, then I think it will just concatenate all of them?)
2. It would skip any expensive equality checks and https://github.com/pydata/xarray/issues/5381

This would also drastically improve `open_mfdataset` by default. It will be pretty backwards-incompatible though.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1588461863
