I don't think that's accurate. OSTree doesn't touch /home from what I remember. It is only concerned with /usr and to as minimal a degree as possible /etc. People likely still want snapshot and rollback for their actual _data_ as well.

Exactly, I think block/filesystem level storage are potential complements.

Many competently-maintained systems already have backup solutions for data though.  In fact, Anaconda defaults to having it on a separate partition in some configurations precisely so that one can just blow away the root partition and preserve /home.

Also, remember than on an OSTree system, /home is just a symlink to /var/home - *all* local mutable state lives in /var.
