[dns-operations] TLDs allowing zone transfers

I have myself noticed that the list of TLDs allowing AXFR changes over time.
But when a new country shows up in that list it usually doesn't last
long. It looks more like a technical oversight than a deliberate decision.

For example .MV is quite recent.

Frequently, only one or a few of the authoritative name server allow AXFR.

I have also noticed that some TLDs that used to allow AXFR, closed the
loophole at some point to reallow it later.

Which sounds like technical mistakes or plain indifference.
