As I said in another email, we're missing a Gerrit feature that would allow us 
to re-target a review to a different branch.

The model whereby the devs don't have to care about the release branch has 
worked for us in the past. That's what we used in the Perforce days and used 
to up until the recent after Gerrit came along. It's a tried model.

Do you mean "release team cherry-picks into release"? That's the model we used 
to have.

The drawback is that the changes of release are all duplicated in stable.

Let's do it then for this release. We can look into a different process later, 
maybe in a smaller repository or a less critical release.
