L23network module is a interface naming scheme agnostic.
Only bridge and bond interface name protection found -- You can't call bond
or bridge like 'enp2s0', because this name reserved for NICs.

It's interesting project. Proposed format for network configuration, so
Project too young. And doesn't allow to configure some things, that
L23network already support.
Main problem of this project -- is a approach to change interface options
options. They doesn't use prefetch/flush mechanics as in the puppet. They
just executing commands for change, instead in most cases. Such approach
doesn't allow re-configure existing cloud properly, if one under production
I can support config format from os-net-config as additional network scheme
format too, but, IMHO, this hierarchical format not so convenient as flat.
NIC mapping, in Nailgun, already implemented in the template-networking. If
wee need use it for another cases -- ask Alexey Kasatkin, please.
