I think status quo is generally "do whatever upstream does by default,"
which is slightly different than either of those. It may be (2) if
upstream is that smart, but it's different than (1) in that we don't
actively suppress parallelization if upstream enables something by
default.
My conservative inclination would be towards (1).
