If this group is used then the uses should also be updated. If it is not used then it can be deleted.

What I would like to do is get some consistency into the display of modules as listed here: https://doc.semantic-mediawiki.org/modules.html

Looks like it is not used

Something is using it: https://doc.semantic-mediawiki.org/modules.html
