Eh, maybe – that’s institutionalizing a) the continuation of exactly the same thing, which might not even be the right call and b) bad topic naming.
Having zero friction here is, I think, the wrong call. How about something more like a hint:
This topic was automatically closed because it was super duper long, like seriously!
Feel free to continue the discussion in a new topic.
Where “new topic” is equivalent to pushing the new topic button.
