I'm not sure if we thought about this before, but the 
os-virtual-interfaces API isn't deprecated with the 2.36 microversion:

https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/virtual_interfaces.py

Neither is os-attach-interfaces:

https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/attach_interfaces.py

Until we had virtual device tagging in 2.32, VirtualInterfaces would 
only be used for nova-network, but with vif tags we store those on VIFs 
in the nova DB, so os-virtual-interfaces could be used to list those. 
However, os-virtual-interfaces doesn't return the VIF tags in the 
response....seems we missed that with the 2.32 microversion. I'm not 
sure how useful that use case is anyway. Plus get_vifs_by_instance isn't 
implemented for neutron, so you'd get a 500 error from this API today 
anyway...

For os-attach-interfaces, we need that to attach/detach interfaces to a 
server, so those actions don't go away with 2.36. We can also list and 
show interfaces (ports) which is a proxy to neutron, but in this case it 
seems a tad bit necessary, else to list ports for a given server you 
have to know to list ports via neutron CLI and filter on 
device_id=server.uuid.

So I think we're OK with os-attach-interfaces (even though it does some 
proxying right now), but I'm thinking we should be deprecating 
os-virtual-interfaces.
