Hey all! Short post, I promise. Just wanted to share the community managed document of features you need to contact Salesforce to enable or disable. This document covers many of the features and functionality that require contacting Salesforce, but not all. As new releases come about, there will also be new items that need to be added to the list.
The Doc: “Features that Require Contacting Salesforce”
Big thanks to Mr. Doug Ayers!
