• Query Store is to query performance metrics what Service Broker is to message queuing; it's just a standardized, optimized, and extensible way of doing something that many of us have been doing for years. It's good at what it does (archiving, aggregating, and visualizing query metrics and plans), and I don't see a need to deploy any of the equivalent in-house stuff myself and others have built in the past that do basically the same thing. What really great about getting everyone on Query Store is that developers can then create SSMS plugins that we all can share.
