### Open future Questions:
- Should peerdas-devnet-7 included [EIP-7892](https://github.com/ethereum/EIPs/pull/9423), BPO Hard Forks?
- Alternately, should a pre-determined blob increase schedule triggered by a BPO mechanism (as proposed [here](https://hackmd.io/@ralexstokes/blob-acc-2025#Blob-schedule-for-Fusaka)) be included in peerdas-devnet-7?
