Upon further review, I see no reason for this extension.

5xx errors are intended to authorize client-side workarounds, including
the delivery of stale content.  That is, in fact, the only real  
between 4xx and 5xx codes.  If this needs to be clarified in the httpbis
drafts, then it should be an issue on httpbis.

We don't need a cache-control option to authorize what should already be
authorized by the HTTP status code.
