I'm from PLCT Lab and am currently trying to port a patch regarding RISC-V Zce extension support onto the repo, but found that this repository is quite outdated compared to upstream. Are there any plans to merge some of the changes?

We don't have an active project manager for this project at the moment, so the roll forward's are not as frequent as I would like. I'd encourage you to get involved. By coincidence, the next meeting is in two hours time (15:00 UTC). Details in the calendar at the bottom of this page: https://www.openhwgroup.org/working-groups/
