I think that a submission flag would work as long as the drawbacks that you noted could be overcome. Generally we allow 'standby' jobs to be exempt from other queue limits and allow all users to access them. So, we would also want the preemptible flag could also be seen by the priority plugin so that it can not count those jobs against queue limits. I think that would provide the same benefits as the queue implementation, at least for how we use standby / preemption.
That said, there are a number of use cases that can be solved by overlapping queues (exempt / expedite, whole cluster DATs), so that could be considered a benefit of that approach. Exempt / expedite could probably all be done through accounting / the priority plugin. We should probably talk more about DATs where we want to be able to let a user run on all nodes on a cluster that we've split into multiple queues.
