In a utopian world, Frontier would have something like a public-accessible (but read-only) Trello board that had features going through stages Planned, Designing, Building, Released (or whatever stages they wanted) and a suggestion submission system that went through a visible lifecycle where developers were able to interact with the submitter.
However, Frontier is a mature company with its own operating model and that model precludes significant interaction with the customers outside of the CM team. We may not like it and we may think there are better ways of doing it, but Frontier are not likely to change.
