Disabling predictable interface names

According to [1] predictable interface naming can be disabled with a 
symlink to /dev/null or by providing net.ifnames=0 on the kernel command 
line. It seems like symlinking to /dev/null isn't working any more.

Is symlinking to /dev/null supposed to still work? We are seeing this on 
Atomic Cloud images where the symlink is in place but net.ifnames=0 
isn't on the cmd line so we are getting ens* interface names.
