TechFlow reports, Ethereum Foundation data researcher Toni Wahrstatter responded to Vitalik's earlier point: "If blob space is full and there's no way to fall back to calldata without paying excessive fees, the entire Ethereum ecosystem (including L2s) becomes more expensive."
Vitalik subsequently stated: "I don't think using calldata as a 'fallback' for blob space is a healthy pattern we should encourage. It would be wasteful if rollups end up maintaining two separate code paths. It's better to cap calldata and take this opportunity to increase blob space further."
Earlier report, in response to Ethereum Foundation data researcher Toni Wahrstatter's analysis on "whether Ethereum's block gas limit should be increased," Vitalik Buterin replied on X: "I lean toward using an EIP to increase the cost of calldata—perhaps reverting to the original 68 gas per non-zero byte. Now that we have EIP-4844 blobs for data-intensive use cases, it will mitigate worst-case data bloat and create more room for increasing gas limits and blob count targets."
