REAPER used to have a similar system where people could vote on feature requests, but it was shut down eventually (before I started using it, so I don’t have first hand experience).
I think the problem is that it creates the expectation that the highest voted request will be implemented first. This can put a lot of pressure on the developers and creates a lot of frustration for users if it doesn’t happen because the request doesn’t fit the vision of the developer.
Like Henry Ford allegedly said “If I had asked people what they wanted, they would have said faster horses.”
So while this resource is probably really valuable to the developers, it might be difficult to get them to acknowledge it publicly.
