Description
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.

Research direction
Start at xarray.open_dataset() and its existing drop_variables option. Trace how variables are selected when opening NetCDF files, then determine the intended behavior for an include_variables or read_variables option. Done means callers can list a small set of variables and the other variables are ignored.
