Good luck! Let me know if you have questions

[binarybaron]

We need to ensure we keep all serialization logic exactly the same to remain backwards compatible.

Hey @binarybaron I have started working on already can I opened WIP PR or should open PR after its full implementation?

[binarybaron]

Please open a WIP PR. This is also not quite trivial so maybe another contributor will jump in and you can work on this collaboratively.
