Stack can be only used to combine multiple coordinates into one coordinate, e.g. `data[x, y, z] -> stacked_data[a, z]` with `a` as a multi-index of `x` and `y`.

In this case, we do not have shared data with coordinates to combine.  
Instead, multiple independent DataArrays should be concatenated along some dimension.

The most similar methods to this one are `xr.concat` and `xr.combine_nested`.
However, they do not allow to implicitly rename dimensions and force-delete non-shared metadata.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,489825483

OK, then this can be closed, since this function should actually remove metadata for me :)

For example, lets consider a dataset with:
- dimensions:  
`(""obs"", ""features_1"", ""features_2"", ..., ""features_n"")`
- variables:  
`x1 (""obs"", ""features_1""), x2 (""obs"", ""features_2""), ..., xn (""obs"", ""features_n"")`

Now I want to stick those side-by-side to get an array `x_combined (""obs"", ""features"")` with `features = features_1 + ... + features_n""`.

Generally we try to keep all of xarray's functions ""metadata aware"", rather overriding metadata. So the API feels a little out of place to me.

Maybe you could share a little bit more about your use case for this?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,489825483
