i think it's a solid recommendation,
It means every registrant, who doesn’t know about DNS, has to create
host objects for glue and whenever the ISP changes nameserver names
(eg gets bought, sold or merges), or IP address, the ISP has to talk
to the registrant to fix things at their registry. I can promise you
those in-domain name servers will quickly become very unreliable.
not. the rest of the paragraph you quoted six words from above was:
i think it's a solid recommendation, but can only be a SHOULD not a
MUST, both because of the installed base / long tail, and the
impossibility of enforcing it, and the market needs of parking lots.
it's not a "has to". i expect it either won't be used when a sale is
possible, or will be removed prior to such sale. i see fujiwara's
proposal as a way to reduce distributed system complexity for those who
can behave this way, and strictly as a recommendation.
