In particular: 1. We want to allow a coordinate named `""foo""` with different dimensions than `(""foo"",)`, in order to support reading all possible netCDF files into xarray. 2. We want to allow indexing with coordinates that are not dimensions. With this second change in particular, it should not be a problem to have a multi-index level with the same name as a dimension. It is true that this change will introduce an inconsistency between appropriate keys for use with `sel` (indexed coordinates) and `isel` (dimensions). But I think this is basically inevitable.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,979316661
