> The current task framework is good for the use case where we want to run identical tasks
according to a target resource's assignment. However, realistically, we want things like:
> - Each task partition can correspond to a different task
> - Some task groups shouldn't have a status corresponding to them; they should be able
to take on additional task partitions dynamically
> - There should be some notion of independence, in that a target resource (or lack thereof)
can say that arbitrary task partitions can be assigned to arbitrary live participants
> This is a pretty involved undertaking, so this will encompass some subtasks.
