I've seen this issue come up a few more times recently, so I wanted to ask: in lieu of a "full fix" (a la https://github.com/pydata/xarray/pull/2405, with deep data model changes holding up the PR), would there be support for a partial coordinate-renaming-based fix? I'd imagine something like the following:

To read in netCDF like the following,

(note the problematic isobaric(station, profile, isobaric)), one could specify a kwarg to xr.open_dataset to rename it,

python ds = xr.open_dataset("my_problematic_file.nc", rename_vars={'isobaric': 'isobaric_coord'})

thus giving
