So, I see what you mean by banned now: the policy indeed bans the possibility to impose a specific way of obtaining your workload on every site. I think that is a good thing.

Okay, I will raise this point in the afternoon. As an alternative we can not ban anything in the policy related to obtaining a workload. This means that some of the images will try to connect to the batch system and we have to make sure these images are not run or won't affect the infrastructure at Nikhef. Of course this also means that these images will fail when they are started at Nikhef. If they want, other sites can do the same for images that will try to get their work from pilot job frameworks.
I'm not sure how successful this intervention will be. In previous discussions multiple sites did not like the idea of VMs prescribing the way they wanted to obtain their workload.
