According to OP Labs CEO Liam Horne, Ethereum core devs have a call coming up this Thursday to discuss getting EIP-4844 to be considered for inclusion (CFI). CFI does not mean "included" in the next hard fork. What gets decided in Shanghai is a separate process.

However, given 4844 and withdrawals both span the across the CL and EL layers, there does seem to be good reason to consider it for Shanghai.
