I assume we'll add a test for this in the SDK repo once it flows there (would be nice to have a test which validates that we do print out a RID - always.

That was what I was thinking, but looking at it again, I think something in here makes more sense. I'll look at adding something to check the host output includes a RID with no SDK and doesn't with a mocked SDK.
