(Most do, many do not. There is NO reason why not.)Since this list is NANOG, it is reasonable that it has a North American bias but remember the Internet is worldwide. I do not know how it is in the USA but there are many parts of the world where ISP do not have a delegation of in-addr.arpa and therefore cannot pass it to their customers. (It is also common to have many levels of ISP, so you need to go through many layers before reaching the RIR.)
Seems this needs to be fixed, then. Not my problem.
Requesting rDNS means "I don't want to receive email from Africa".
