Absolutely. I think that transparency and some sort of declaration of intent or "vision" is important to avoid misunderstandings about what something IS or at least is intended to become.
Your questions are great and there are plenty of examples of people choosing personal enrichment at the expense of people who thought they had a say or stake in things - but when it came to it they really didn't. These kinds of situations need to be avoided as they can create incredible grievance.
I was suggesting "workflows" which is a bit of a dev term, but basically something could start out as one thing and morph into another over time (when it's ready and meets certain pre-conditions). For example, you could create an "Incubator" that could mature and morph into a "Community" or a "Club" or a "Company" depending on ownership and governance models that might evolve as it grows and matures.
