The new text for MSR's is as follows:

"8.7 Multi-homed Host Support (MEDIUM)
The CPE Router MAY support RFC4191 on its LAN interfaces.  Small
consumer embedded multi-homed hosts in the home may not have
configurable routing tables.  The CPE Router can communicate More
Specific Routes (MSRs) to these hosts to allow them to choose a
preferred router to send traffic to for traffic destined to specific
prefixes configured through manual configuration.  Advertisement of MSRs
through RAs is turned off by default."

I take it back.  It's interesting in the other cases as well.  Two CPE
routers attached to the same link will exchange their prefixes with MSR
advertisements regardless of whether the RAs from the service provider
have PIO options in them.  As they should.
