Sorry that my reply comes so late, I have been away for a short while and I am catching up. I am not sure what we can do right now but will definitely pass the request over.
Roadmaps can be tricky. It is something we've all expressed interest in before - but I can say the resources side is usually due to a lot of things needing to be under the radar, and that wouldn't change due to a roadmap. I know the patience it takes when seasons are getting longer, and things will become clearer in time, but this will still be relayed onwards.
