I noticed Jimbo has also sysadmin flag recently. The change was about 2
months ago on enwikiversity.[1] The reason was "need to view deleted
revisions", but sysadmin group does hold no rights about deleted revisions.
Instead they have globalgroup[permissions/membership].
Originally, Jimbo doesn't need to have sysadmin flag and doesn't have root
or shell access. So sysadmin bit should be removed.
Best regards.
