2844 used to move these variables to ds.coords rather than ds.data_vars, and allowed saving of ancillary_variables via the encoding attribute. It was decided to drop that since ancillary_variables are linked to variables rather than dimensions like most of the other CF attributes.

The specific behavior mentioned in the original post (describing ancillary_variables in the output) might work better in cf-xarray's ds.cf.describe method.
