Hi @luckyDog , thank you for your thoughtful feedback!
While the proposal date was our initial target, we agree it’s a stretch now and will make sure to only create the proposal to the NNS once we feel the community has digested this updated whitepaper plus parameters, and we all had appropriate time for the conversation on it 
The milestone based development work goes back to comments like @bitel911 's “Milestone-Based Funding” and “Q5: What rights and privileges does a participant get for contributing to an SNS launch, and what should this participant expect to gain?” here Reviving the SNS Framework: Addressing Current Challenges and Exploring Solutions , and @Leadership 's https://forum.dfinity.org/t/helping-sns-daos-succeed-milestones-based-treasury-withdrawals/47152 that we agree with.
In the onicai SNS, we thus propose that development work is funded in a similar process based on milestones and community review calls, i.e.
- At the end of each quarter: Public review call with the community and the development team of the goals and development progress, plus review of the proposed goals for next quarter.
- If the goals for the last quarter have been reached, the development team puts in a proposal for 50% of the development budget for last quarter (that’s the 50% after delivery).
- If the goals for next quarter have been agreed upon, the development team formalizes them and puts in a proposal for 50% of the development budget to do the work (that’s the 50% before delivery), and then starts working on them.
- At the midway point of the quarter, e.g. 6 weeks into the quarter, there’s a public update call with the community and the development team to give an update on this quarter’s development work.
We envision this process to happen every quarter to give actual development transparency to the community. The development will thus work a bit like DFINITY developer grants, with regular updates and reviews.
Please also see the section “Milestone-based treasury withdrawal model” in the whitepaper (https://www.onicai.com/files/onicai_SNS_Whitepaper.pdf).
In addition, please see " onicai SNS Treasury" in the Whitepaper where we propose the idea of staking and then dissolving treasury tokens on a quarterly basis such that mostly only what is needed for the SNS’ quarterly budget would be available. From the whitepaper section: “To limit the immediate availability of the SNS treasury’s ICP and ONICAI holdings at genesis, the development team plans to propose that the majority of these tokens be staked. The staking mechanism will cause the ICP and ONICAI to unlock gradually over time. That way, only a reasonable amount of funds can be allocated at any given time for the SNS budget, e.g. on a quarterly basis, ensuring that the treasury remains solvent and can sustain the SNS development and growth. At the same time, the maturity from staking can be used as rewards for governance participation…”
