This is my experience too. I frequently require a single queue for some very specific task but it does not form part of a greater application.

My current work (data engineering) is such that I don't have a relational database instance that it would make sense to use instead. SQS is very straightforward and just works.

None of this is to say that I would necessarily advocate for a user-facing app to be _based_ on a queue-based architecture.
