Mbin doesn't directly merge threads together, in the Piefed sense where the comments from all threads appear on the same page. It does however group duplicate posts together. For example, I'm looking at this, I don't see the comments on the other threads here, but I DO see there's four other threads linked.
Tried attaching an image showing how it looks, not sure if that'll show up in Interstellar/Piefed/Lemmy though.
