We do have stable interface names, through the exact same way (/lib/udev/rules.d/75-persistent-net-generator.rules) as we've had for many years. I proposed to switch to ifnames a few days ago (https://lists.ubuntu.com/archives/ubuntu-devel/2015-May/038761.html), if you want you can already try that by deleting /etc/udev/rules.d/70-persistent-net.rules and booting with "net.ifnames=1".
