If you specify -J0 to turn off jittering, it will cause all
hypersampled rays to compute the same value N times. This is
probably not what is intended if hypersampling is specified.

Actually, I now think this is good behavior -- even expected/desireable when I
ended up needing it to behave exactly this way. The benchmarks were able to take
advantage of jitterless hypersample to scale results to the performance of the
machine with that exact behavior.
It does beg the question, though, as to how one might want to specify a regular
patterned non-jittered hypersample. That would be a feature request, though,
not a bug.
