I see that python-omemo 1.0.0 is a complete rewrite: https://github.com/Syndace/python-omemo/blob/main/CHANGELOG.md#100---1st-of-november-2022
This removed the omemo.backends module. I also see that the upstream has archived python-omemo-backend-signal repo, around the same time: https://github.com/Syndace/python-omemo-backend-signal So, probably time to remove this from the archive, clearly they don't intend to support the new API.
