> If a pod has a reservation on a node the quota change could prevent the reservation from ever be used:
>  * queue A with 1000 GB quota
>  * usage of queue A is 900 GB
>  * pod that needs placing is 64 GB, large node is needed
>  * node is not available and a node is reserved
> Quota change is made:
>  * quota is lowered to below 900 GB the reservation cannot be full filled until usage drops below new quota - 64GB → result remove the reservation
> There might be more cases that need checking
