[members-discuss] New (silent) reverse dns checks

Out-of-order provisioning is in 98% (my experience, see further down) of the cases a bad idea, and in transfer cases simply ends up blacking out the resource for an unnecessarily long time. 

I personally started verifying presence of running zone at the receiving operator when I was one of two people running redelegations of SE children, and while verification was cumbersome, the net result was that the least empowered, the end users who just wanted their domain to work, in the overwhelming majority of cases were transferred with a minimum of down time. When we did not verify, the usual order was "no email for a week, because it all bounces". 

Since then, people quit using email, and started living their lives online instead, and the systems people came up with all manners of clever OLTP-style provisioning tools. 

Or more succinctly: I think "out-of-order provisioning" is a very weak argument 2019. 

And, open resolvers have no place on authoritative servers. Full stop.

    why does it make sense? I don't see how one follows from the other.
    Registrars doing such checks are generally frowned upon as they get in
    the way of out-of-order provisioning.
