The functionality, as far as I understand, is already in the `open_mfdataset` function in the `data_vars ='minimal'` argument, in this case variables without `concat_dim` are included without adding the dimension. The current default is `data_vars ='all'` which include all variables with the added dimension. If the desired functionality shouldn't implicitly add new dimensions shouldn't the default be set to `'minimal'` instead? 

I think this is a very non-intrusive solution since it only affects the `open_mfdataset` function, and if you for some reason want the old behavior it is still there. An alternative way is to rewrite the `_dataset_concat` function I guess.

This is my first time attempting to contribute, does this sound like a good idea? I can try to make a pull request but would very much value some input first.","{""total_count"": 2, ""+1"": 2, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,314764258
