Yeah, the Activity class has high level read_file/write_file methods
which could be probably replaced with a non-datastore implementation.
But not all activities are using the high level API.

Ok. But afaict that's not what Martin is proposing here.

Using the datastore and providing a Journal view would be certainly
the most straigth forward implementation, but the level of integration
with the rest of desktop would be very low. Maybe it's fine until we
get a POSIX compatible datastore though?
