For context, I’ve been actively mapping since 2019 or so and never got to discover the old help site (my main reading were Wiki and the mailing lists), so I don’t miss any of its features (good or bad). I could imagine that a good deal of posters in the Help and Support category would have similar experience.
Whatever one’s experience was, the current feature works differently than the rest of the current Community site (I’ve had at least two gotcha moments with it), makes the whole site even more complex and confusing than it already is, and I don’t see a clear benefit of the “answer” format (in the Stack Exchange manner) compared to the standard forum-like interface we have elsewhere.
Apart from the missing activity tracking, the main problem is that users confuse the two paradigms, and will inevitably continue to do so. See for example this thread, where everyone was at loss whether to “answer” or “comment” or “reply”.
