[ceilometer] events are deprecated - true?

Hi, I was wondering if events are still deprecated? https://github.com/openstack/ceilometer/blob/master/doc/source/admin/telemet... "Warning Events support is deprecated." But how to handle all those service events if ceilometer will drop the support to validate and store those messages in gnocchi? Is there any longterm plan how to handle billing then? Why should this feature be deprecated? All the best, Flo
