What is the impact of the new default that "both the primary and standby databases receive query requests"?
Is there a performance gain? Is it more reliable? How exactly does it work? Does it have any negative impacts / things that need to be considered compared to the old behavior? Please explain why this was changed. Was this change listed in the change notes for 11.4?

"Introduced at ArcGIS Enterprise 11.4. Starting at 11.4, highly available deployments will have both the primary and standby databases receive query requests by default. This behavior can be modified by setting the useROConnectionForQueries property as false, which ensures that both the primary and standby machines only use the primary database for query requests. If this property is not defined in the system properties, or is set to true, the default behavior will be used."
