As would I.  .asia was mentioned on this list on the 3rd of May.  Purely
by coincidence, my cron job is set to 0300 on the 3rd of each month, so
it was already included.  If it had not been, there would have been a
gap until I heard of a new tld and did another zone transfer.  I'm not
sure when .travel was activated, but when I first heard about it it was
already in "my" root.

I assume that if you had been one of my unfortunate users you would have
mentioned it at the time?

I know it's brittle, so I try to be careful.  If the cron job fails, I
would know it the same morning.

I'm not advocating that anybody else do this (much less make it an OS
default. :-)  It is simply a method that I've found helpful in our small
network.
