Rebooted a Ubuntu 16.04 VM. My virtual ethernet card device is now “ens33”. Of course.
1) you can fix it per MAC address (RTFM ;) ) 2) not assigning static names automatically is actually a good security measure. Honestly not a systemd issue.

Why are random interface names a good security measure?
-
To avoid firewall rules on like ethX to allow traffic on spurious interfaces plugged on locked systems and evaluated.
-
Mmh, if interface names went with hardware like BSD you’d know when a USB interface is plugged in because the name is different? Consistency through hand-waving is a bit weird.
-
I want consistency only when I explicit assign driver *and* MAC address to an interface name, everything else should be a random throwaway. Systemd and udev behave like that and it’s fine by me.
