Called Verizon today. They still offer a vacation suspension; and yes they still add the numbers of days you request the suspension to then end of your contract.
They are not extending the contract, I am. I requested that my phone be disconnected so that I will not have to pay for the three months that I spend overseas. Plus they are helping me out: I can't use my phone and they did not charge me a monthly service fee and I did not have to cancel my contract. However, because they are allowing me to suspend payment and modify my contract it is only fair that they add those days/months to my contract.
Congress did nothing to inhibit this type of transaction.
