> The problem is that Redis tries very hard to position itself as a persistent data store

What are you talking about? On their website, the top 3 use cases (under the Platform menu) are: caching, streaming, and session management. Literally all of these three are volatile.

I haven encountered a _shocking_ number of people who treat Redis as a persistent store. There mere mention that it has some kind of persistence machinery is enough to convince some that is therefore durable and stable and should be treated like a DB.
