Your browser can just download the plugin from Google the same way Firefox does. No permission required since you're not distributing it yourself. This is no different than the case of the Silverlight plugin. There is no reason why Netflix would need to do user-agent sniffing - the EME API is built around request access to specific "Key Systems" (eg. Widevine) by well-known-name. If they do user-agent sniffing that's an entirely separate issue, and is just as much as problem in the Silverlight case.
