Apparently not. From


  * The mechanism for providing stable network interface names changed.
    Previously they were kept in /etc/udev/rules.d/70-persistent-net.rules
    which mapped device MAC addresses to the (arbitrary) name they got when
    they first appeared (i. e. mostly at the time of installation). As this
    had several problems and is not supported any more, this is deprecated in
    favor of the "net.ifnames" mechanism.

And in


  some 4 weeks ago I sent a first proposal to change persistent network
  interface naming away from our current
  /lib/udev/rules.d/75-persistent-net-generator.rules (which is
  inherently racy and doesn't apply to all virtualized environments) to
  udev's "net.ifnames":
