I know. Despite the fact, IIRC, that (with the exception of .COM) they are fetched by ICANN via zone transfer.

On ICANN’s side, what more would it require standing up a name server and sharing TSIG keys?  If DNS UPDATE were also implemented, it would address the timeliness issue (if the registries were willing to play along).

Of course, CZDS users would likely need to change their code.  However, this wouldn’t have to be either/or — both could be done with the benefit of using IXFR being only getting the diffs (and, potentially better timeliness).

One can dream…
