DHCP snooping prevents rogue DHCP servers. I have only seen a handful of switches in orgs configured for hard limits MAC/lease per port. OOB most things will dish up leases at will, how else are folks spinning up countless bridged VMs, containers, etc in workstations.

I appreciate you sharing that it doesn't seem new to you, could you share some of your examples so we can learn from your experience also?

PoCs like this are cool. This is a valid and potentially catastrophic attack against network segments. One should study and consider countermeasures against such attacks on your turf. Python and Scapy are super cool and if you haven't had a play it's well worth your time.
