In dewiki, we have discussed to add an individual abusefilter group to increase the number of experienced users to aid in filter management, and reached consensus in a discussion on the edit filter noticeboard:
https://de.wikipedia.org/wiki/Wikipedia_Diskussion:Bearbeitungsfilter
This discussion has also been advertised on the administrator noticeboard, the bureaucrat noticeboard and the project helpdesk.
This group should have the following permissions:
- abusefilter-modify
- abusefilter-modify-restricted
- abusefilter-access-protected-vars
- managechangetags
Adding and removing users should be managed by bureaucrats. Admins should retain their abusefilter permissions as is.
