While this can be fixed (could be tricky), we should deprecate it: it is convenient but probably too neat now that multi-indexes levels have their own, ""real"" coordinates (see https://github.com/pydata/xarray/issues/6293#issuecomment-1259228475). It should be preferred to explicitly chain `concat` with `assign_coords` (and `set_index`) like the last line in your example.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1402168223 https://github.com/pydata/xarray/issues/7148#issuecomment-1272481643,https://api.github.com/repos/pydata/xarray/issues/7148,1272481643,IC_kwDOAMm_X85L2Idr,10194086,2022-10-09T07:56:00Z,2022-10-09T07:56:00Z,MEMBER,Thanks for the report. There was a recent release (2022.09) with many Index related bugfixes (including MuliIndex) - could you test this? ,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1402168223
