I agree that it is a very bad idea to ignore DNS caching. It was built-in on
purpose.

I'm sorry for disappointing you.
The behavior I describe is standard for last ~ 20 years 1987 (RFCs
1034/1035/2308). If you don't agree with standard then you cannot use DNS
technology as standardized. Here I'm not sure if other Fedora users would also
welcome non-standard behavior.
If you feel that the standard is broken then *please* continue with discussion
on IETF's dnsop mailing list:
https://www.ietf.org/mailman/listinfo/dnsop
come on stop trolling that way because you know exactly what i am
talking about by "broken client software" - the point is that with
caching on each and every device you lose the oppotinity clear central
caches for whatever reason and make the changes visible on all clients
in realtime
