This looks like a brilliant idea, thanks!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,207962322

Coordinate reference systems (crs) are an example of attribute which is always valid after selection, arithmetic, or even reduction since they apply to the coordinates of the DataArray. A global option to keep certain attrs (like ``crs``) would be very useful to downstream libraries like salem.
