'Suggest Features' Forum Section

I've often wondered why there isn't any 'Suggest Features' sticky/subforum. I know it was asked for a while back by someone but I remember it being shot down.

A lot of other forums like NMT, Tvix etc.. have them and it's a great opportunity for providing user feedback with a view to improving the product in the long run. I appreciate that the frequency of daily posts here means that one can simply post in the main forum without it disappearing within 48 hours. However, infrequent visitors don't always get to see such feature requests (which they may never have thought of and thus couldn't search for) and to which they don't have an opportunity to discuss or add their support.
