I think that Whitepaper and roadmap are the most important documentations am therefore developers should publish them
Of course, these are important documents for any project. But agree that it is better when there is no White Paper and a Road Map, but there is a unique code of its own and a unique idea. There are many projects that have white paper, road maps and a beautiful website, but there is no active development.
I dont understand why you think that it is better not to have Roadmap and Whitepaper.. I also think that it is very important part of any project because it gives clear understanding to all community members
