So what.
What you just described is what I said about using 0.0.0.0 and 255.255.255.255 and the fact that those addresses are not routable.
There are other aspects of DHCP that are routable.  Like a DHCP helper / relay agent using the DHCP protocol to communicate with a remote DHCP server, or when clients use the IP they previously received via a DHCP helper / relay agent to communicate directly with said remote DHCP server.
How the DHCP protocol is being used doesn't mean that the DHCP protocol is unroutable.  Especially when the same DHCP protocol is used in a routed manner other times.
