> In order to make best use of local recovery, we have to forward the set of preferred allocations to the {{DeclarativeSlotPoolBridge}} where new slots are matched with pending slot requests. At the moment this is not the case and this means that whenever we try to recover locally while not having all slots available, we might do wrong scheduling decisions.
> In order to improve the situation, I propose to forward the set of preferred allocations to the {{DeclarativeSlotPoolBridge}}.
