I assume for all these that it's expected that we don't use a provider name?

That's correct. Non-relational services—such as API Hub, Cosmos DB, Event Hubs, Notification Hubs, Redis Cache, Service Bus, and others—do not use traditional ADO.NET providers. The documentation at this link outlines which prefix is injected into a .NET app along with its corresponding provider. Additionally, in the related issue thread, it was noted that a workaround is to define a custom connection string that already uses a null provider.

Now that we're adding a 1st class support, does it help to set a provider name though? How does that get used by folks? If it is intentional that we don't set a provider name then it would be good to capture that reasoning in a comment.

It looks reasonable to me - but I think we should get a second opinion from folks who know better how these are used to understand if any require provider names. My very cursory understanding here is that the provider name could help some generic component auto-discover a registered provider and use that to connect. Which seems like it could be an important thing to provide better built-in support.
