I think most of the resources when moved from contrib to in-tree are marked
as unsupported. Adding routes to an existing router by multiple stacks can
be racy and is probably the reason use of this resource is not encouraged
and hence it's not supported. You can see the discussion in the original
patch that proposed this resource https://review.openstack.org/#/c/41044/

Not sure if things have changed on neutron side for us to revisit the
concerns.

Also it does not have any update_allowed properties, hence no
handle_update(). It would be replaced if you change any property.

Hope it helps.
