this function looks like it is in the middle of a bunch of override impl of a
delegate.

Sorry I don't quite understand your suggestion here. Are you saying this
function should not be placed here? But it's in the same order with the base
class ContentMainDelegate.

yao@, it looks like there are 2 sections of overrides, separated by an empty
line.

The first group is "just" overrides, and the second one is "Create*" overrides.
Perhaps, you should move your method into the first group.

Like this? 

(Also, The first half is public in the base class, and the second half is
protected.)

   content::ContentPluginClient* CreateContentPluginClient() override;
   content::ContentRendererClient* CreateContentRendererClient() override;
