I think it would be totally reasonable and consistent with the netcdf data model to read dimension coordinates from parent groups when they are missing on the requested group.

I'm currently working around this by loading the root group & the branch group with two separate calls and then merging the resulting datasets. It's ugly b/c I have to manually associate the 'phony_dim_x' dimensions from one group with the other.

Maybe I can find the time during quarantine to make an attempt at resolving #1092 https://github.com/pydata/xarray/issues/1092, which I think would facilitate resolving this issue as well.

Another option would be to allow the group kwarg to be a tuple of group names, and load_dataset could yield a (flat) Dataset including both the root and the branch variables.
