You're right, I missed this. The test result shows that this command
succeeds. Do we really want to allow other nodes to be affected with a
blockdev-add? Wouldn't it be cleaner to just forbid the combination of
limits and throtte-group?

I'm not sure, you could argue either way. But there should be a test to
check that the semantics won't change.

If we're going with Stefan's suggestion that anonymous groups shouldn't
exist, then the question is moot anyway.

Ok, fair enough.
