I think a list of acknowledged/considered issues is very much needed and would be great in terms of communicating with the players, but a roadmap is (iirc) said to not be planned and I think it's a good decision. Roadmaps are cool to see, but in reality bring a lot of unnecessary problems - players are sure to be disappointed when something previously planned proves unviable and has to be scrapped. And they're either committing to the roadmap and lock themselves in this plan or remain flexible, in which case the roadmap becomes useless. No wins here.
I agree that roadmaps bring a lot of headache many times, but some insight into what direction the game is taking in relation to the feedback and hot topics would be doable without a roadmap. E.g. no point in discussing turn-based and RTwP if it's set in stone and there is no intention of looking at that option. Same goes for character creation, action economy, etc. There is plenty of potentially good feedback out there, and with some direction it would be very valuable instead of getting lost in a myriad of threads on this forum, steam, reddit, etc.
