> How do you measure that? This is a serious question, one that affects DNS operators. If you have a way of determining how many enterprises are negatively affected as a new gTLD rolls out, that would be very useful information.

My advice to enterprises is to consider the following:

Let the value to your enterprise of resolving the new domains be X
Let the value at risk due to resolving the new domains be Y
Let the cost of disabling new domain resolution be Z

If Y > X-Z  then the obvious choice is to turn off resolution of new domains.

Since X and Z are both zero the choice is obvious.
