Getting a complete future vision and putting it into 1 proposal is too big. Because what do you do when you agree with most, but disagree with one? Splitting into pieces sounds a better route if you want to go through governance (which I like, because it gives some sort of control back to the community).
I am strongly in favor of voting on the entire document. It clearly defines the Hub’s purpose within the interchain as well as the mechanism by which to realize that vision. The governance architecture proposed in Section 5, “Cosmos Governance: A Forum for Sovereign Interoperability” explicitly outlines a structure to ensure that the “community has some sort of control” and provides a map that can be used to navigate the ever-present gap in decentralized governance between accountability and control. As for your question, “what to do when you disagree with one part of the proposal,” well: that’s what discussion periods are for!
Each piece of this proposal is interconnected (like the interchain itself). While I also would like to see governance functionality whereby sentiment can be expressed toward modular segments of proposals, we are not there yet. Haste is required to align on a vision in order to build the social and technological infrastructure needed to bring about the Integration phase of Cosmos.
Beyond the pragmatic motivation for leaving the whole intact, there is also the call to action within the proposal. Compartmentalizing aspects of this document dampens this call for community members to organize themselves under a unified vision because it reduces the availability of context, which is so important for on-boarding and authority delegation.
On Osmosis we have set the preference to do 1 gov proposal : 1 topic.
The governance needs of Osmosis differ greatly from the needs of the Hub. Osmosis, being a DeFi appchain, has greater need to adhere to a corporate governance model (Vitalik, " DAOs are not corporations: where decentralization in autonomous organizations matters") in order to move quickly and efficiently. Insofar as the interchain has one, the Hub is a sovereign. Sovereigns require an overarching structure under which public infrastructure is built, aligned projects are funded, and authority is delegated. It is only right that this structure be ratified on-chain. Given our current governance module raising a signaling proposal is the most effective means by which to ratify such a document.
There are certainly actionable items that should be voted on as individual topics in governance but manifestos, constitutions, or documents that align a constituency under a structure which connects an entire ecosystem do not fall under that category.
A whole is greater than its parts. The interchain is better for everyone when the Hub is unified Hub. If there is disagreement with a piece of the document, let’s hash it out during this discussion period, not dilute the document by breaking it into separate proposals.
