Docs / Confusing warning about multi-node when enabling Masakari

Reading the docs it mentions that I need only two or more compute nodes
Now, I have 3x nodes (1x of them has control+storage+compute, 2x of them have storage+compute roles)

```bash
# sunbeam enable instance-recovery
WARNING: This feature is meant for multi-node deployment only.
[..]
```

Is there any reason for that warning to show?
It is a confusing message. I do have a multi-node deployment
