The Google API allows specifying multiple components of the same type for component filtering
e.g.

administrative_area:VA|administrative_area:Arlington

However, this is currently not possible using the GoogleV3 geocoder since the method requires that components be passed in as dict.

One way to add this functionality might be to also accept a list of tuples:

components=[
    ('administrative_area',  'VA'),
    ('administrative_area', 'Arlington')
]

I can make a PR if this is within scope.
