Not to mention that if the next step on the roadmap were "Alphabetize function calls in foo.h", someone would be likely to hear a constant "You haven't done that yet? Why not, it's simple, here I'll do it for you, just get it done, c'mon you're holding things up, what's wrong with you, you suck..."
Roadmap could be good. But I'm 83.7% sure it won't change anything from the perspective of the developers.
