I'm going to make several backups, and try this one with great suspicion. MacOS 10.12.2 bricked my iMac requiring reload from backups twice.

Hopefully the graphics switching improvements aren't limited to the 2016 MBPs. Sierra also has switching issues on earlier models including my 2015 MBP causing it to switch to the discreet GPU for applications that didn't cause the switch on previous OSes.
