Yes, indeed. It was a sad time in the history of the IETF. Fortunately the IETF seems to have sobered up from that specific ... lapse. It's much harder to get approval for protocol-specific use of TXT records these days. The IESG is more on its toes, and there is (again) a DNS Directorate.

It is interesting to note that there is a dedicated RR type for the SPF function, SPF RR type, but that is deprecated. Instead TXT RR type should be used.
It is kind of backwards.
Fighting the use of TXT records for various function would be a life-time struggle.

Hi Anne-Marie!
I too was unaware of any conventions for doing this in the _DNS_, but I _am_ aware of the prolific abuse of TXT records for various and sundry kitchen-sink-like purposes, so your words didn't surprise me at all.
If you _do_ find signs of this type of data being put into the DNS, please share them with me.
For anyone who thinks that using TXT records to solve your custom problem is a quick and simple solution, think again. Or contact me, and I'll drag you out of that misconception ... And mind you: new record types are dirt cheap, and very easy to create and register. đ
Cheers, /Liman

ns.se@lists.iis.se 2025-05-08 20:36 [+0200]: Hej,
Jag har en frÄga till alla DNS-gurus i vÀrlden. Det har ju dykt upp en del saker som man kan stoppa in i dns, som security.txt och robots.txt. Det senaste jag hör de var om llm.txt. Finns det och hur övertygar man en AI om att respektera respektive kringgÄ en sÄdan? Hur mÄnga txt finns det i vÀrlden. Liman och andra, som försvarat dns frÄn onödig börda genom Ären, hur ser ni pÄ det?
MÄnga hÀlsningar,
Anne-Marie
