Having consistent interface names on servers that have several is useful, but we already had that option. The interface names they generate are not only hard to remember, but not terribly useful as they’re based on things like which PCI slot they’re in, rather than what their purpose is. You want interface names like wan0 and DMZ, not enp0s2. Of course, you can set it up to use useful names, but it’s more complicated than it used to be, so while the systemd approach looks like a good idea on the surface, it’s actually a retrograde step.
