There's been no discussion of it being a top level entity.

No one is actively working on Roller Derby at the moment, but one aspect
of it that I still think is important to capture is tooling for
snapshots of *data* in addition to "snapshots" of the OS.
There are definitely cases where one wants to do that in concert. And
also very strong cases for allowing them to be separate.
If a kernel upgrade goes wrong, you very likely don't want to rollback
your mysql database.
But on a major version upgrade, I can see it being very handy to also
snapshot one's data. Data backups though are quite well covered by a
wide array of existing free and proprietary software.

I don't think the rpm-ostree/Atomic model is applicable to general
Workstation use at the current time - not having the ability to add or
remove packages is much less practical for the freeform development
That said, I think it *is* applicable for the specialized Workstation
use case of a replicated "Corporate Standard Build", where each client
machine is supposed to be running the same software. For that though,
the lack of a PackageKit backend is a large gap, though it's of course
possible to script updates.
