Re: NODES table - conditional compilation for op_depth
Seems like this will make things even more complicated. I'd be in
favor of *not* switching to NODES unless/until the op_depth is done
properly. If you switch early, then you're going to require another
format bump to reset all the op_depth fields to their proper values. I
don't think an early-switch to NODES before proper op_depth
computation will buy us anything.
