I lost a more comprehensive response due to an application crash... IMHO, asking this in DNSOP is not the right place. Judging from messages about spam, some rely on PTRs and some rely on other approaches. That's a better discussion, not one in front of DNS people. In the sense that no RFC can "force" an operator into publishing anything it doesn't want to publish.

Absolutely not (recommend ISPs should delegate). While it would be good if an ISP offered this to interested parties, don't expect to saddle the operator with yet another service that expects the customer to reply/provide out-of-band information. I know I wouldn't bother. Simply because I do not, for my home life, have any DNS servers. For one, my ISP provides me one IPv4 address, from a DHCP pool. For two, I don't want to spend my life beyond work replicating what I do for work. And with the kids these days...with their mobile devices...I'm sure they don't either.
