Probably not but it's simpler to specify that rather than saying it's
mandatory only if you need it and it might be useful to know if
everything is a flat collection of threads or a flat collection of
cores, it seems better to get the information in there if we can in case
the DT is fixed.  Single core systems are the only ones where it's
definitely never going to be helpful.
