What's the app data backup/restore story on GrapheneOS?
My understanding is that even with pseudo-D2D (device-to-device) transfers Seedvault doesn't backup everything[1].
Are there more-functional, non-root, local (non-cloud) alternatives?

Not without root, no
Seedvault is still woefully insufficient, but it sounds like there's work being done to replace it. I can't imagine the enterprise crowd will overlook that and I'm hoping the Motorola partnership enables faster development.
