nit: PlatformMojoInterface's'... or maybe PlatformMojoServices (I slightly
prefer latter, as what we're accessing through this are mojo services)

Done.

+public:
+    PlatformMojoInterface();
+
+    const mojom::blink::ResourceHintsHandlerPtr& resourceHintsHandlerHost();

nit: why we add suffix 'Host' here? Just resourceHintsHandler() (or
getResourceHintsHandler()) looks enough to me

[Charlie Harrison, 2016/06/16 11:00:20]

Done.
