Yes! This is a great approach, and I'd be happy to see more examples like this in the wild. This is similar to the same way Phoenix PubSub works, with the PubSub application starting a pg scope as part of its supervision tree, that client PubSub servers can join if configured to use the pg adapter.

I was a little bit flippant in my initial comment, but my main criticism was of libraries that don't support any sort of hooks like this into their supervision strategy, and instead rely entirely on a global and static supervision tree, usually configured using app config.
