> 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}}.
