Of course, since it's non-standard it only benefits their own reverse proxies, not any regular proxies that might be used elsewhere (unless those happen to be running the patched Squid for some reason). Varying on Accept-Encoding is very useful for cache hit rate as well. Reference: http://www.mail-archive.com/squid-dev at squid-cache.org/msg07066.html
