I don't believe the feature described here would have been possible when the issue was originally raised, since Groups 1.x has never supported Workflow integration (which is separate from revisioning).
However, we now have Groups v2/3, which do support Workflows, and it seems this issue predicted the future: The "Group Content Moderation" permissions matrix for workflows under "Edit group type permissions" only applies to "group content," not to the group entity itself.
This means that group entities will fall back to sitewide permissions for determining workflow access, which can easily lead to group roles having access to more or fewer workflow permissions than intended when they are editing group entities. Worse, roles can lose edit access to group entities entirely if they do not have a suitable sitewide permission for workflow transitions.
This is something I'd be interested in seeing resolved. If anyone thinks it'd be a bad idea to unilaterally impose these permissions on group entities then perhaps it can be a site settings checkbox somewhere to toggle this feature.
