Actually I agreed that it's not a "must have". But as I mentioned, I do consider it useful (for me: very useful).
The point is that since topic cloning is a default feature (which to me seems just as useful as post cloning generally speaking, but actually a lot less useful to me as using topic cloning requires many more steps to achieve the result I want/need) then why not include post cloning: IF IT IS EASY to IMPLEMENT (and that's something I can't judge).
I'm realistic about this: 1 opinion (mine) is not going to make a difference and seeing the lack of enthousiasm for the idea, I'm not even going to waste time and energy in promoting it. I'll save that to downvote really bad ideas
