From a domain name typed into a configuration panel on the home gateway, updated in the same manner (find the zone cut, 
find the MNAME, send a DNS UPDATE)?

Presumably if a domain name is not specified, no DNS UPDATEs occur.

I'm not commenting on the need or proper desire to have matching PTR/AAAA records for the addresses at the provider 
edge, I'm just saying that the mechanism Mark described seems plausible.
