I propose this change because I have found that these two traceflags are necessary for an optimal configuration of Query Store. During a failover, I saw the wait type QDS_LOADDB track 3 minutes of wait time, meaning that Query Store was waiting to load and queries could not run. This behavior is prevented by Traceflag 7752 and I propose that this documentation includes at least a mention of these, considering that best practices are often referenced by consultants and corporations who set up this new feature. I hope I provided sufficient description of what they do.
