Vitalik: It is best to restrict calldata and take this opportunity to increase more blob space

Ethereum Foundation data researcher Toni Wahrstatter responds to Vitalik's previous viewpoint: "If the blob space is full and cannot fallback to calldata without paying too much fees, then the cost of the entire Ethereum ecosystem (including L2) will be higher."

Vitalik responded: "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 code paths. It's better to limit calldata and take this opportunity to increase more blob space."
