Well the requesting router could announce the route.  ISC's client
has hooks that allow this to be done.  That is, after all, how
routing is designed to work.  The DHCP server usually is sitting
in a data center on the other side of the country with zero ability
to inject approptiate routes.

The DHCP relay could also have injected routes but that is a second
class solution.

A CPE announcing the route is fine as long as the ISP controls the CPE.

If the CPE is controled by the customer, then the ISP's problems are
similar. They need to find a way to filter the CPE's announcement so
that it can announce only the prefixes delegated to it.
