[Eugene But (OOO till 7-30), 2017/04/14 14:30:51]

Are there any includes which now can be removed
(native_app_navigation_controller.h, native_app_metadata.h,
authentication_service.h, authentication_service_factory.h, chrome_identity.h)?

[pkl (ping after 24h if needed), 2017/04/14 16:59:23]

Yes. Done.
