BTW, one alternative I was once considering for the scale down case is
merging state handles that are backed by different physical files in one
logical state handle, using something based on `MultiStreamStateHandle`. That
would require minor changes in how the backends currently iterate the handles
and some calculation of virtual offsets near the `StateAssignmentOperation`,
mapping the old physical file offsets to the new logical offsets in the stream
that gives a consecutive logical view over the files. Then, the whole code
would never again deal with this detail. Wonder if this is worth the effort?
