clearing etags when gzipping

In ngx_http_gzip_header_filter there is a call to ngx_http_clear_etag.
While this spec-compliant it loses the benefits of etags.  Two
alternate approaches would be:

 - Only clear the etag if it's strong.
 - Append ";gzip" to the etag, remove it from
   incoming "if-none-match" requests.

Would a patch to implement one of these be welcome?
