When data Artisans introduced <https://www.ververica.com/blog/queryable-state-use-case-demo> Queryable State in Flink, one of the use cases was explicitly removing the need for external key-value stores. This mirrored Confluent's earlier <https://www.confluent.io/blog/unifying-stream-processing-and-interactive-queries-in-apache-kafka/> introduction of Interactive Queries in Kafka Streams, and they certainly saw querying of streaming state as a possible alternative to traditional data stores.
