Cleanup.

Can you please stop arguing about review feedback that is clearly right? This is not fixing 
anything. The Fixes tag is used to decide if something needs a backport. And every backport has 
a chance for a regression. So adding a Fixes tag to something that is not fixing a bug is actually
hurting.
