You clearly have no understanding of route aggregation which just made
it's entry into the soho.

The router will set up it's own DHCP-PD prefix delegation for downstream
routers. Without a /56 or larger it is very hard to do automatically.

It is not "wasting" it is "required" for proper operation of a routing
internet. You can't just NAT a downstream router and still have IPv6.

People buy extra wifi routers at their favorite shop and *will* plug the
cable into the "Internet" port. With IPv6 and DHCP-PD they will still
get working IPv6 internet. Great!

Cheers,
