The point is not to vote but to debate.
Debating is fine, but if an agreed on (and fully debated about) method of voting could be arrived at to achieve results in terms of the process, it would be even better. See Please vote in the Solid stakeholders poll
Unfortunately I can’t do this justice in a single response. The short answer is that we’re detailing the MUSTs now in the normative draft of the specification at https://github.com/solid/specification. One thing that’s worthwhile to point out is that we’re in the process of portioning out the core client/server protocol (Solid Protocol). The purpose is to allow a more flexible evolution of ecosystems between clients, over a more consistent and well-defined interface.
Hope that helps. If you’ve got questions on specific MUSTs or MAYs I’m happy to chime in on those.
that makes sense to me, thank you for clear response!
