Vitalik responded that Ethereum still has a contract size limit due to DoS risk considerations, which may be lifted after EIP-7864

In response to the community's discussion on "Ethereum still setting a contract size limit," Vitalik Buterin stated that it is due to DoS risk considerations. He mentioned that after the Ethereum state structure is upgraded to a unified binary tree (EIP-7864), it is expected to achieve unlimited contract size, but the Gas fees and mechanism design for deploying super large contracts still need to be addressed. Currently, based on the cost of creation per byte, the actual contract limit is about 82 KB.
