We've had it running in production on the Nectar cloud for the last 12 months. The work I did made it upstream, so you should be right to go from at least Queens.
You'll just need to set something like this in your Trove config:
nova_proxy_admin_user = trove
nova_proxy_admin_pass = <pass>
nova_proxy_admin_tenant_name = trove
remote_nova_client = trove.common.single_tenant_remote.nova_client_trove_admin
remote_cinder_client = trove.common.single_tenant_remote.cinder_client_trove_admin
remote_neutron_client = trove.common.single_tenant_remote.neutron_client_trove_admin
cheers,
Andy
