Considering the intention behind the Google document is to enable support for existing Ajax applications, and not the cornerstone of crawlability of newly built apps, probably not.

Also, the same document that's quoted in defence of these Web (unfriendly) Apps is https://developers.google.com/webmasters/ajax-crawling/

Where in the first section of that document: https://developers.google.com/webmasters/ajax-crawling/docs/... There is this:

"If you're starting from scratch, one good approach is to build your site's structure and navigation using only HTML. Then, once you have the site's pages, links, and content in place, you can spice up the appearance and interface with AJAX. Googlebot will be happy looking at the HTML, while users with modern browsers can enjoy your AJAX bonuses."
