Wait a second, if you decided to become intermediary in the protocol then you are supposed to add value, not take away the features that already exists.
Although its not clear from the article itself, my gut feeling is that some big enough client arm twisted them to support it before they sign the contract again
Implementing the HTTP/1.1 caching mechanism at the proxy server is delightfully simple if you just ignore it entirely. But if you decide to do some caching on your own, you better implement the semantics in the way the clients and the servers expect it to be. Which is not simple at all if you're doing the caching to eke some performance improvements.
