I have added a lengthy review of PepperSync and updated my original post.
Summary:
The proposal is $461,000.00 for the
pepper-synccode, and nothing else. I find the library itself has not demonstrated a large value add to the ecosystem. I find the claimed cost (2x senior engineers for 15 months) to be an exaggeration or wasteful. As a voter, I do not think this proposal is a net benefit to the Zcash ecosystem, so I would vote AGAINST funding.
