I have added an RFE for this here: http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=121259
Basically our issue is that we use Fixlet Severity as key for whether we require users to install a patch. Recently a spectre/meltdown microcode_ctl fixlet from the RHSA channel was superseded by one from the RHEA channel which doesn’t have a fixlet severity. Now we either have to re-architect our dashboards or try to create a new system for addressing these issues without opening the floodgates on all RHEA/CEAA content.
