I am in 100% agreement with DaveGlanville and grant_jenkins. Features like this may be great for your customers without established brands, but they're absolutely not appropriate for customers that have established brands that don't want users to be creative outside of the parameters set by branding teams. Customers absolutely should have the ability to turn off these sorts of things. This feature does not solve problems for a lot of your customers, it just creates new problems. grant_jenkins's point about the removal of Discard changes and how that will affect this is spot-on.
Like DaveGlanville asked, is there any sort of year-long panel where Microsoft discusses potential changes with actual customers to see if there is a widespread desire for them? The way Microsoft uses its products internally is not an indicator of how customers in other industries use them.
