1) Are we still maintaining GYP files?
2) Any reason why this doesn't include instance_id_driver_java like above?  Is
it transiently included?

I guess not
(https://groups.google.com/a/chromium.org/d/topic/chromium-dev/NZkPr-CXvQ0/dis...),
but since I've already updated it, it seems it may as well stay?
It's not a public dependency in GN, whereas in GYP IIRC all dependencies were
public.
