It is not clear to customers what the situation is with this module in current bundles, see SUPPORT-7226. The goal of this ticket is to try to remove as much config leftovers as possible. Ideally, only the JAR needed by commenting should be visible.

Pointers from grooming:

• do we only use code from forum, or also config, in commenting?
• if we make it a JAR and remove the MD => how can commenting check that it's here or not?
• should we release a new commenting major version with the code forum needs included?
