These were intentional design choices to keep xarray simple, but in principle you could layer cf convention handling on top of xarray.

Nor does it bring along bounds variables when extracting variables from a dataset, e.g.
```
        double time(time) ;
                time:long_name = ""time"" ;
                time:cartesian_axis = ""T"" ;
                time:calendar_type = ""NOLEAP"" ;
                time:bounds = ""time_bounds"" ;
                time:units = ""days since 0001-01-01"" ;
                time:calendar = ""NOLEAP"" ;
```
When a variable using the `time` dimension is extracted from a `Dataset`, the `time_bounds` variable is missing.

Is this also an intentional choice or something that xarray could/should support? Or does already and I've missed how to invoke this.

Edit: I've just realised, how is xarray supposed to ""bring along"" another variable in a DataArray object? I'll leave this query as maybe there is a solution? Have a `bounds` attribute similar to the `coords` attribute?
