Just came across the answer to your first original question:

This is limited by the constant MAX_TRACE_LEVEL_LIMIT, defined in
configbackend.h; its only purpose seems to be to provide for a "sanity check"
of the max_trace_level setting, so basically it should be possible to pick any
other aribitrary value like, say, 1024, or remove the check altogether.
However, there will be *some* limit to it imposed by the memory available, and
POV will probably crach if it reaches this limit. It will also affect render
time, of course.
