Query-based reopening relies on the presence of a (meta, time) index to be efficient. This index will be built by default for new collections when featureFlagTimeseriesScalabilityImprovements is enabled. However, existing collections that get upgraded will not have the index unless the user has explicitly created it, and further, the user may drop the index manually. If the index isn't present, we should disable query-based reopening, and nudge the user to create the index via log message.
