The draft clearly says what ICMPv6 errors are returned by the CPE
Router, so it's not like the CPE Router is not responding to any ICMPv6
request. Existing IPv4 routers do have a ping disable feature where the
router is configured to not respond to pings.  I also said on this
thread that if the CPE Router does respond to pings, the CPE Router
needs to rate limit incoming ping reqs.

It's a router so it must generate numerous other ICMP packets in
response to certain incoming packets. So not responding to pings doesn't
buy you anything.
