Done.

+ public:
+  // Returns the routing ID for the RenderView proxy for the guest in the
+  // owner's guest process. This creates a new proxy if one does not already

What is "owner's guest process?"  Do you mean "owner's renderer process?"

Yes, I've removed this API.

+  virtual int GetGuestProxyRoutingID() = 0;
+
+  // Sets the size of the guest WebContents.
+  virtual void SizeContents(const gfx::Size& new_size) = 0;

+  // Called when the GuestProxyHost is about to be destroyed.
+  virtual void WillDestroy() = 0;
