Unfortunately, this seems like the only good way to handle EIP-4844, given that there might be e.g. consistently 1 other blob tx per block with a high tip, which wouldn't cause the blobfee to escalate and thus creates a pre-EIP-1559-like tip market against a blob tx that takes up all 6 blob slots. The block producer's local incentive is to include the tx with 1 blob and a high tip instead of the tx with 6 blobs and a low tip. Using only 3 blobs per tx fixes this by ensuring that if the blobspace of a block is filled up with other txs, it must have at least 4 blobs, which means the blobfee will escalate and we'll have a EIP-1559-like market as intended.
