Does the new SDK expose a pluggable backend abstraction similar to durabletask-go?

Hi,

I noticed that durabletask-go exposes a clear Backend abstraction with official SQLite and PostgreSQL implementations.

Is the .NET Durable Task SDK intended to support similar pluggable backend implementations in the future, or is the recommended direction to use Durable Task Scheduler for all self-hosted deployments?

I'm trying to understand the long-term extensibility story for self-hosted backends.
