      We should document the Mongoid policy for handling $ and . fields (introduced in MongoDB 5.0).

      In summary:

      • In MongoDB's interface (not specific to Mongoid) $ and . fields are special "hidden fields" that can only be accessed with special "shadow" operators.
      • Mongoid query operators / field names will behave as normal post-MongoDB 5.0
      • The field function will not allow . and $ in field names; Ruby doesn't support such method names anyway.
