Ole said: why do you need a global address on the WAN interface because

RPF (Reverse Path Forwarding) will fail and if RPF fails for a router,
due to security concerns, the router should drop the incoming packet. If
the WAN interface of the CPE Router does not have a global IPV6 address,
how is RPF going to work? RPF needs global IPv6 addresses.

I'm confused. How would RPF fail if the router will normally have a default route out the WAN interface?
