How can I check if an object is a dict_keys() in Python?

My current options are:

1. seems bad style:

dict_keys = type(dict().keys())
is_dict_keys = isinstance(foo, dict_keys)

2. overzealously matches:

from collections.abc import KeysView
is_dict_keys = isinstance(foo, KeysView)

There's no way to import this from the types library and there's no documentation about it in the Dictionary view objects section of the documentation.
Is there a better way to do this? Is dict_keys intentionally excluded from the documentation?
