In the osapi name from the request is always converted to display_name. There is no logic for appending a launch_index, although I also remember that something like that was done before.
Code for generating hostname is here: https://github.com/openstack/nova/blob/master/nova/compute/api.py#L653 The display name is sanitized here: https://github.com/openstack/nova/blob/master/nova/utils.py#L1076 There is no per tenant uniqueness check, although that might be useful, as well as the option to add .tenant_name onto the hostname.
