1) EIP-4844 is built on the basis of withdrawals;
2) The specification has been completed after more than 9 months of iteration;
3) Interoperable repository with stress testing;
4) There is a completed specification for KZG trust facility ceremonies;
5) The KZG library supports Node, C#, Rust, Python, etc.;
6) Devnet V3, scheduled to be launched on November 30, will support 6/9 major clients.
The CFI is not meant to be included in the next hard fork, but given that both EIP-4844 and withdrawals span the CL and EL layers, there seems to be good reason for inclusion in the Shanghai upgrade.
