Depends if they are actually going to do anything with the forums. If the answer is just going to be along the lines of 'we are not considering updating the forums at this time' then no, it would just be a waste.
I see. But that's not a q&a session then plus they should be looking in this forum section for ideas. I understand where you are coming from and I get how frustrating it is to rarely see a change to the forums, except for the moving/deleting of forum sections but I don't think they should do one unless they have decent answers to give.
Good to see some jmod responses to this. I reread what I wrote on the first page and I sound really disillusioned with how they treat the forums. Hopefully if they do do a question and answer, they will provide some informative answers.
