I've often debated something like this for Atomic Host.

I think it'd make sense to extract from flatpak for sure.  Offhand
is there anything desktop-app specific aside from the appstream stuff?

We could have it be a build-time option for ostree, so people
who are doing "fixed purpose embedded" without wanting Docker/OCI
could just turn it off.  Or alternatively it could be a new shared library?
Maybe something git-submodulable.
