> Cron job resources are treated as an addition rather than a replacement during cron schedule update. This leads to double counting of the updated schedule, which creates a problem when a role is hovering around its quota limit. We need a new API in the QuotaManager to properly handle this case. Something like {{QuotaManager.checkCronUpdate()}} that would properly subtract existing cron schedule consumption before comparing against quota.
