Is there a way to persist `attrs` during arithmetic options? I find myself writing a bunch of boilerplate to transfer the wealth of metadata included with most netCDF files.

I realize that adding a module-level or `DataArray` instance-specific `maintain_attrs` configuration flag (as discussed in #131, #988, #1271) could be problematic, but this strikes me as complexity worth adding. The current approach of dropping all metadata (not just units) seems heavy-handed and unintuitive for new/casual users. As you mentioned in #1271, better to have stale metadata than no metadata at all.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,264049503

While I understand the logic of dropping units during certain operations, it makes attributes unusable for storing other miscellaneous metadata, e.g. on data provenance. As a recent xarray convert, this behavior has been frustrating.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,264049503
