- Default behavior: only autoconfirmed users (existing functionality)
- Add optional per-wiki configuration to restrict it to a specific user-right
Note: As of now, there are no immediate plans to make use of this setting. We plan to leave it at the default for all source wikis. We think it's still a good idea to be able to quickly change this via configuration, if the need arises. This setting will also be useful for 3rd-party users (e.g. to lower the required user group).
