It would probably add confusion for live players because it would take however long for tgc to go through feedback, consider how it works with their plans for the features, etc.
If it stays in beta we're already used to things taking time to implement, things not even making it to live etc.
Plus we do have lots and lots of live folks who visit and leave feedback regardless if they're testers so tgc are probably getting a small, but significant amount of feedback for the feature already to work with.
Of course if it is something that makes it to live and people have concerns and so on then there's always live feedback open to us there.
A community vote could be interesting, and you could suggest it in beta feedback even, but I don't know how feasible it would be for tgc to do that with something that's not finalised without it causing a lot of confusion and misinfo too.
