Since the global group 'abusefilter-helper' belongs to the wmgPrivilegedGlobalGroups, 'abusefilter-maintainer' should also be added.
|operations/mediawiki-config||master||+1 -0||Add 'abusefilter-maintainer' to wmgPrivilegedGlobalGroups|
It's a site-security mandated change, not community-mandated. No, I don't think consensus should be required.
As for the signoff, I'm happy to deploy it, it doesn't make sense to have less-privileged group there than a higher-privileged one (I mean, AFH < AFM, and AFH is already there). Treat it as signed off ;).
