              <pre>disabling the use of the 240/4 NetBlock. The cost of this software
engineering should be minimal.

Yes, let's say that the cost for Vendor A could be minimal: they will
remove some lines in the code for version X.Y and release version X.Y-EzIP
without bugs triggered by removing those lines. Then, we, the operators,
would have to plan the upgrade of all of our routers, spend days
programming the upgrade, spend nights in maintenance windows, maybe pay for
remote hands, etc., just to extend for a few more days the inevitable agony
of IPv4.

Thus, the cost of the so-called EzIP is not minimal.
