Ethereum core developers are under pressure to potentially scale back the scope of the upcoming "Glamsterdam" upgrade to meet a mid-year launch target. During the 173rd Ethereum consensus layer core developer meeting, it was discussed that if an interoperable version of EIP-7732 is not ready by the end of February, it may be excluded from the upgrade and deferred to a future hard fork. Additionally, the Consensys Teku client has faced node performance issues during mainnet stress testing, impacting progress. Other key points from the meeting include the need for a minor API review for EIP-7928 and the February 4 deadline for submitting proposals for the Headliner EIPs of the Hegota upgrade. Some client teams have already made headway on updating the library for EIP-7688, indicating ongoing efforts to keep the upgrade on track.
