Are chunk files going away?

Are chunk files going away?
I see that there will be a "unified LOD" geometry type coming up,
but I don't see many changes to the chunk file generation code
and the files are named "Old" now.
Just thought I should ask.

Not knowing what to expect with the new update, I just kind-of
assumed that part of being easier to use, that one of
the first change would be unattended chunk file generation by having
AtlasMesher::write error back out to the console function
where function arguments would define how to increase the
error metric and/or the tree depth before the file was processed again.
Or at least error out so it can process the next file.
I also assumed maybe there would be some kind of separate log
file for terrain processing, just as a separate record of how the terrain
was processed.

I think I will look into these changes, been meaning to create a new
console function entry that gives you a choice of using signed or unsigned
height fields.
