I am just back from the Ops Midcycle where Heidi Joy Tretheway reported
some data from the user survey.
So if we look at deployments with more than 100 servers NO ONE IS USING
NEWTON yet. And I scream this loud. Everyone is still in Liberty or Mitaka.
I am just struggling to upgrade to LBaaSv2 to hear that is already going
into deprecation. The feature Zhi is proposing is important also for me
once I go to production.
I would encourage devs to listen more to operators feedback. Also you
devs cant just ignore that users are running still Liberty/Mitaka so you
need to change something in this way of working or all the users will
