      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?

      When reading mixed relaxed and canonical extended JSON in relaxed parsing mode (for instance: { "_id": 1, "encrypted_long":

      { "$numberLong": 123 }

      }), our parser loses type information making it impossible to roundtrip the Long value correctly. This will be a breaking change, but perhaps we can offer a compat mode until the next major release.

      We should perhaps even consider that parsing should never be relaxed vs canonical, and reserve relaxed mode only for generating extended JSON.
