Are you sure they would break http/1.1?
Doesn't this section (13.1.1) possibly cover the dodgy backend server 
situation?

"If a stored response is not "fresh enough" by the most restrictive 
freshness requirement of both the client and the origin server, in 
carefully considered circumstances the cache MAY still return the response 
with the appropriate Warning header (see section 13.1.5 and 14.46), unless 
such a response is prohibited (e.g., by a "no-store" cache-directive, or by 
a "no-cache" cache-request-directive; see section 14.9)."

I'm not saying that there shouldn't be "special configuration options" for 
these things, but I'm just not totally convinced that it would be breaking 
http/1.1
