On product: Guidelines for Web Content Transformation Proxies

If we mandate sending X-Device-* headers, this should be done with a mention they could get deprecated in the future (per ACTION-897 and ACTION-912).

But is there any point in having the headers sent? If the content is mobile-optimized, the CT proxy shouldn't transform it anyway, and if it isn't, it's unlikely the CT provider will do anything with these additional headers.
