I think you should update the helptext too, which currently says that
it's enabled if SCHED_SMT is enabled.

And yes, it may be that there is no measurable performance downside,
but this feature has been discussed and under development for a long
time now, and I'd like the default to try to limit the impact since it
makes little sense to most people.
