Thanks for tagging me @sonya; yes, I think any proposal that has the Foundation receiving all funds (even if there are contracts in place for development) could jeopardize broader decentralization, and as you suggested I wouldn’t want the Foundation to be a single gatekeeper.
And thanks to @zooko for his post above and giving the community his perspective. The Foundation would only support proposals that:
a) don’t rely on the Foundation being a single gatekeeper of funds
b) don’t change the upper bound of ZEC supply
and c) have some kind of opt in mechanism for choosing to disburse funds (from miners and/or users)
We could suggest a proposal within these guidelines, but like @zooko I would prefer to see proposals from others in the community first.
