This is an excellent point and something I'd like to see discussed more broadly. Gzipping and minimizing assets pales in comparison to simply not sending a bulk of the content to begin with. It would be great if browsers could set a header value when requesting a page, and if supported, the server could respond with content that's already in what would otherwise be the so-called reader format.
