Could we move this to be a fail for the "not ignition_staging" variant and a
pass for ignition_staging? If it ends up being complicated don't worry, this is
fine.

I thought about doing this, but the problem is that the "default" variant is
also failing (only passing for ignition_staging and ignition_turbofan). And I
was wary about adding a section for the "default" variant. That seemed strange
to me. WDYT?
