278389733 MDU6SXNzdWUyNzgzODk3MzM= 1754 Opposite of `drop_variables` option in `open_dataset()` 1067637 open 0     3 2017-12-01T08:18:21Z 2019-11-14T22:50:18Z   NONE      

Not so much an issue but more a feature request. xarray.open_dataset() has the drop_variables option, perhaps the opposite could also be useful, e.g. include_variables or read_variables (i.e.; only read the variables which are listed and ignore the others).

I often work with large NetCDF files (>100 variables) out of which I only want to read a few; it is easier to list those few variables than to create a list with the hundred(s) of variables which I don't want.
