Support Feature Policy

Could Cloudflare please support injecting the feature policy header, like how to does with HSTS? It doesn’t need to have every single feature that exists, but something like being able to set geolocation 'none'; microphone 'none'; camera 'none'; payment 'none'; (maybe like how you can turn on minification with checkboxes?) which would help protect user’s privacy by making it so that the site can’t access the camera and mic and etc if enabled, would be nice.
