From Newsgroup: comp.protocols.dns.bind

Yes but I think the rfc1537 refers, and the recommendation always was "localhost." hostname, which refers to name "localhost", not "localhost.domain". Then I guess, this was already wrong in the O'Reilly "DNS and BIND" book (have to check that), which I remember using as a guideline to set up our first domains/zones. And from that, the setting was copied later on to all new domains too.

Thx for the info, had missed this one and actually we have that minor misconfiguration too. Have had since 1995 when started our nameservers

Yes, it used to be recommended -
https://tools.ietf.org/html/rfc1537#section-10
But not any more, because -

I also only found out about this recently(ish) - https://www.dns.cam.ac.uk/news/2017-09-01-localhost.html
