Hello. Currently, local user groups are listed at Special:ListGroupRights. Would it be possible to create a Special:ListGlobalRights page, to easily display global user groups and the associated rights? The functionality currently exists on https://tools.wmflabs.org/meta/globalgroups/ but an on-wiki equivalent would be ideal. This page could be linked from Special:ListGroupRights, and also show which groups are active on a given project through wikisets.
The reason for this is just transparency, so it is easier for local users to see and understand.
