I usually hate deprecation warnings because I think they are ineffective and time-wasting. But this case may be worthy of an exception. In addition to console warnings in browsers and the alert in the spec, it might be useful to have a concerted documentation and outreach effort (e.g. blog posts on the topic) as an additional push to get Web developers to stop using sync XHR.
