If a crawler doesn't support Allow, then it's going to see the Disallow: / and not crawl anything on your site. Providing, of course, that it ignores things in robots.txt that it doesn't understand. All the major search engine crawlers support Allow, and a lot of the smaller ones do, too. It's easy to implement.

User-agent: Applebot
