educated and wild guess on my side, the application was crafted and evaluated with pre dencun metrics. This has been one of the (several) challenges for both protocols and advisors during LTIPP program. Since in the PYTH reporting there is no mention of specific delay in integration, I might just be right here but happy to have more details. Also, the byproduct of this result for future program could be that for infra projects a pre-allocated budget might not be the way to got.
Going back to the snapshot, as for the synthetix application, I am, unfortunately, voting against it, as well as the other extention requests in Arbitrum. To quote my previous answer:
In here we have a different situation, which is a potential usage of funds for an infra product, so I could see the merit of the extention. But the mix of the detox proposal + the fact that most of the leftover funds are tied, in my understanding, to lower costs than expected, means that the only real reason to keep Pyth in an extention would be to facilitate his role in Arbitrum. This is something we could advocate for Synthetix and Aave as well, even if their role is different. Again, the vote of the DAO for the detox proposal is more important, and should just be respected by participants.
