[GSoC 2026] Project #6 Cleanup and Refactor Unused Features

[yuntongtre]

Hi! I'm Yuntong, a student interested in applying for GSoC 2026 Project #6. I've been exploring the codebase this week and already submitted a small PR #1558 removing the unimplemented WASM operator source. I had a couple of questions:

1.I noticed some fields marked with unstable prefixes, like _unstable_local and _unstable_remote in CommunicationConfig. Is the goal for this project to stabilize these into proper APIs, or to remove them if they're no longer needed?
2.Are there specific test coverage gaps the mentors have already identified that should be addressed as part of this project?

Thanks for the great project and looking forward to contributing more!

Hi Yuntong, I'm Leon.

Currently, the project has many unstable features starting with "_unstable". These are indeed features added during development and haven't yet reached a stable state, so they're consistently using "_unstable". Regarding whether these features are unused, I think we can discuss this with the DORA team. We will try our best to compile a list of features that are definitely no longer in use, thus creating a clearer list of feature adjustments.

I see that #1558 has been merged. We recommend using this method to find unused features.

Thank you for the clarification!
