This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)

• Having spent three weeks to sign such a simple technical PR has made the test results disappear
• However, the updates are simple enough that I don't think it is needed to restart the tests: let them merge it nonetheless
