Hey Mike, AFAIK, there's no bug/blueprint on LP.
The question I want to raise here is what will happen if I decide to deploy a cluster with one compute without controllers? It looks like a bad UX to me, though it may increase speed of CI gates where one node with one role is enough. Can we ignore the problem above and remove this limitation? Or should we improve it somehow so it would work for one nodes, and will be ignored for others?
