Well, I have some really good news for the tens of thousands of people who visited and expressed their disappointment.
With a simple trip to the Terminal you can turn the chime back on! Literally 24 keypresses and the lovely F-Major cord we have all come to love since 1999 is back.
Open Terminal on your Mac and type:
sudo nvram BootAudio=%01
To turn the chime off:
sudo nvram BootAudio=%00
As a bonus tip, when you plug the 2016 MacBook Pro into power it auto boots. You can control that too by a simple terminal command.
sudo nvram AutoBoot=%00
and to return the default boot behavior when you plug the MacBook Pro in:
sudo nvram AutoBoot=%03
All the commands are using SUDO which require you to enter your administrative password.
