Cross-posting my response to Daira’s Github comments here…
In my personal opinion, this draft ZIP “manifestly violates common expectations of a significant portion of the Zcash community” and should not be accepted.
I disagree.
ZIP 1015 says that “the Zcash Community wishes to establish a new Zcash Development Fund after the second halving in November 2024, with the intent to put in place a more decentralized mechanism for allocation of development funds”. There was no expectation that “allocation of development funds” would be blocked behind any specific protocol feature, other than possibly mechanisms that directly help to allocate development funds — which ZSAs do not.
The absence of an explicitly-articulated expectation in a ZIP does not imply that the ZIP in question can be interpreted as expressing an opposite or counter-expectation.
Furthermore, one could argue that, at the time the community decided to adopt ZIP 1015, there was an expectation that zcashd would be deprecated well before April 2025, thus clearing the path for ZSA activation.
ZSAs in particular are a complicated feature that very well might encounter delays in deployment for entirely legitimate reasons. What if a security vulnerability is found, for example? It is completely inappropriate to hold the lockbox funds hostage to ZSA deployment.
Extenuating circumstances (such as a fundamental security vulnerability) would, in my opinion, be grounds for re-consulting the community. There is plenty of precedence for amending ZIPs (c.f. ZIP 1014).
