Hi, I would like to propose that we do not support the notifications method for automatically creating DNS records in Queens+. This method for achieving Neutron integration has been superseded both upstream and in the charms. By removing support for it in Queens we prevent the charm from attempting to make designate v1 api calls for Queens+ which is a positive thing given it will have been removed ( https://docs.openstack.org/releasenotes/designate/queens.html#critical-issues ). Thanks Liam
