Rejected for the following reasons:
- By now resolute released and submissions are limited to SRU policy
- One problem here is the missing cover-email and going with that an 
indication
   about the series target. (At least "[SRU R]")
- For SRU upstream changes are the preferred approach. SAUCE should only be
   used if absolutely necessary (and explained why). Non-upstream 
changes have
   a high chance to be forgotten moving forward. Especially now that R 
is out and
   everyone concentrates on S/unstable.
