IIRC (hopefully Ian or someone else will correct me if not) the main
proposal to discuss with you was WRT the usefulness of the RCs for stable
releases, since it was felt they didn't provide much benefit to
downstreams.

IOW perhaps it would be just as useful to downstreams and less work for us
(mainly you I suppose) to do 0 or only 1 rc for a point release, based on
whatever is in the branch at the appropriate time. It might also avoid
various delays which the stable release process can currently suffer from
waiting for a push for each rc instead of just once (or maybe twice), which
in turn might help the release timing to be even more predictable.

Ian.
