In the name of optimization, even reuse can be dangerous.  Given the
solutions for integrating DHCP, AAA and EAP which are now IPsec WG work
items, I'm not sure that they could have done worse inventing something new.

Traditionally people have been adverse to the idea of DHCP relays and the
extra latency involved in DHCP exchanges.  Also there is the need for
stable storage in classical DHCPv4 servers.

Neither of those considerations apply to stateless deployments of
DHCPINFORM, though.

The IAB has been looking at issuing some architectural guidance on the
subject of IP configuration.  If you think that there is something useful
that they could do you might send mail to iab@xxxxxxxx proposing what that
is.
