Hmm I think in this case the goal of the roadmap is a search for validation (or recognition, lol, but let's stick with the sunny case.) This can be done but why would anyone want to read it? No one is going to invest in something that can be coded on a $20 plan either. Let's just hope someone reads it and asks some "why" for free and then everyone can move on.

optimism

Publishing this roadmap is what surprises me. I don't care much how they get to the stated goal, but I would think the goal of a roadmap on a website like this is to inform your users of your plans. There doesn't seem to be much information here.
