It looks like this might be changing thanks to the new voting system. Topics in the Feedback & Ideas with the most votes now get fed back to the Products teams:
A quick note on Feedback & Ideas
As some of you may have noticed, we recently turned on User Voting for the Feedback & Ideas category. We are very happy with the initial results of this, and we’re encouraging synchronisation (and sending of traffic) to the category via our social media channels.
What that means is we’ll be sending tweets like this in response to user suggestions, and if the suggestion has already been made we’ll be directing them to vote for the existing topic. I already fed back the Top 10 most voted threads so far to our Product teams, and they were happy for the feedback. We’ll be doing that every few weeks.
Quick clarifier - just because something is a popular request does not mean in and of itself that we will be building it. But it definitely provides a data point and useful context, and can potentially aid with prioritisation.
