Here’s a real world scenario:

When we went from BuddyPress forums to bbPress, we were left with some niche “Project” forums. As opposed to our most frequented forums like “Troubleshooting” and “Development”, these forums were the only ones that actually merited group-integration back when that was the only way to create a forum.

After migrating, it would make sense to couple these forums together with their respective groups again. However, we don’t want to do that if it means changing the URLs, which would not only disturb the user experience as explained above, but also cause some trouble with our redirects.
