On increasing the block gas limit: technical considerations & path forward

Core developers Toni, Marek, Pari, Jacek, Paul, Tim and Alex argue that Ethereum's block gas limit should not be raised toward 60 million gas right now, and that increases beyond 36 million should wait for more data after the Pectra upgrade. They say consensus-layer clients cap gossiped blocks at 10 MiB, so blocks above roughly 40 million gas could fail to propagate and cause missed slots. They point to EIP-7623 and EIP-7691, both included in Pectra, as providing the headroom and empirical data needed for safe increases, and they suggest a first step to around 36 million gas.
